You fill out Form SSA-3820-BK by answering every question about a child’s medical conditions, daily activities, schooling, and functioning in detail, then signing and submitting it to the Social Security Administration (SSA) along with the child’s SSI disability application. The form is the Disability Report – Child, and it tells the state Disability Determination Services (DDS) examiner how the child’s impairments limit age-appropriate activities. Skipping sections, giving short answers, or guessing at dates can delay or sink an otherwise valid claim under 20 C.F.R. § 416.912.
The form exists because SSI childhood disability uses a different legal standard than adult disability. Under 20 C.F.R. § 416.924, a child under 18 is “disabled” only if a medically determinable impairment causes “marked and severe functional limitations” expected to last 12 months or result in death. The Supreme Court in Sullivan v. Zebley, 493 U.S. 521 (1990), forced SSA to add functional analysis to childhood claims, which is why so much of the SSA-3820-BK asks how the child functions rather than just what the diagnosis is.
According to the SSA Annual Statistical Report on the SSI Program, 2024, about 987,000 children received SSI benefits, and roughly 65% of initial childhood disability claims are denied at the first level. A clean, complete SSA-3820-BK is one of the few tools a parent or representative controls that can move a claim from “denied” to “approved.”

What Form SSA-3820-BK Is and Why It Exists
Form SSA-3820-BK, titled Disability Report – Child, is the core medical and functional questionnaire SSA uses when a parent, guardian, or representative files a Supplemental Security Income (SSI) claim for a person under age 18. The “BK” suffix means “booklet,” and the paper version runs roughly 15 pages. SSA also offers an online version called the Child Disability Report (i3820) that asks the same questions in a guided format.
The form is not the application itself. The application is the Form SSA-8000-BK, which captures income, resources, and household composition for the SSI financial test. SSA-3820-BK is the medical half of the file. DDS examiners and the agency medical and psychological consultants rely on it to decide whether the child meets a Listing of Impairments or “functionally equals” a listing.
The legal framework behind every question
Every question on the form ties back to a regulation. The “what is wrong with the child” questions support the medically determinable impairment requirement. The “how does it affect the child” questions feed the six functional domains in 20 C.F.R. § 416.926a: acquiring and using information, attending and completing tasks, interacting and relating with others, moving about and manipulating objects, caring for yourself, and health and physical well-being.
The plain-English consequence is simple. If you write “autism” and stop, DDS has nothing to score. If you write “autism, nonverbal, cannot dress without help, hits self when routine changes, requires 1:1 aide at school,” DDS now has facts that map directly to interacting and relating and caring for yourself. The common misconception is that diagnosis alone wins the case. It does not. Functioning wins the case.
Who must complete the form
Any adult filing for a child must complete it. That includes biological parents, adoptive parents, stepparents in the household, legal guardians, foster parents in some states, and appointed representatives under 20 C.F.R. § 416.1500. A child age 16 or 17 can sign for themselves in limited circumstances, but most claims are signed by the parent.
The consequence of letting the wrong person sign is a returned application and lost protective filing date. SSA tracks the protective filing date because benefits are paid from the month after that date forward, per POMS SI 00601.030. A real example: Maria Lopez called SSA on March 1, 2026, set a protective filing date for her son Diego, but had her sister fill out and sign the SSA-3820-BK because Maria works nights. SSA voided the signature, Maria refiled in May, and Diego lost two months of back pay at the 2026 federal benefit rate of $967 per month.
Before You Start: Documents to Gather
Filling out the form cold leads to vague answers. Pull every document together first. The SSA Child Disability Starter Kit gives a checklist, and DDS examiners will tell you that complete contact information is the single biggest predictor of a fast decision.
You need the child’s birth certificate or proof of age, Social Security number, all medical provider names with full addresses, phone numbers, fax numbers, and patient ID numbers if known, every prescription bottle for current medications with dosage and prescribing doctor, school records including the most recent Individualized Education Program (IEP) or 504 plan, recent report cards, any private psychological or developmental testing, and a written list of every hospitalization with admission and discharge dates.
The reason this matters is that under 20 C.F.R. § 416.912(b), SSA must develop the medical record for the 12 months before the application. If you list a clinic but not the address, DDS may not request the records, and a denial based on “insufficient evidence” is the predictable consequence.
Set up a representative if you want one
If you plan to use a lawyer or non-attorney representative, file Form SSA-1696 before you submit SSA-3820-BK. Once SSA-1696 is on file, the representative can sign the SSA-3820-BK and receive copies of the determination. Fees are capped at 25% of past-due benefits or $9,200 in 2026, whichever is less, under SSA’s fee agreement process.
A common misconception is that you must pay an upfront retainer. Most childhood SSI representatives work on contingency. The consequence of waiting until after the denial to retain counsel is that the lawyer must redo months of work the family already started.
Section-by-Section Walkthrough of Form SSA-3820-BK
The form has six numbered sections plus a remarks page. Each section asks something specific, and each question has a “right” level of detail. The rule is simple: never write “see attached” alone, never write “N/A” if any answer is possible, and always continue answers in Section 6 – Remarks when the line is too short.
Section 1 – Information About the Disabled Child
This section captures identity. Fill in the child’s full legal name, date of birth, Social Security number, sex, height in inches, weight in pounds, primary language, and whether the child can read, write, and speak English. If the child is nonverbal or uses American Sign Language, write that here, not later.
The consequence of misstating language is that DDS may schedule a consultative examination in English the child cannot follow, and a “failure to cooperate” denial under 20 C.F.R. § 416.918 is the predictable result. A common mistake is leaving height and weight blank for a baby. Always include the most recent pediatric measurement, because growth percentiles matter for Listing 100.05 (failure to thrive).
Section 2 – Contacts
Section 2 asks for someone other than the child’s parent who can answer questions about the child’s condition. List a teacher, therapist, grandparent, or case manager with phone numbers. DDS often calls this person when school records are slow to arrive.
A real example: James Carter, a single father in Ohio, listed his son’s special education teacher in Section 2. When DDS could not reach the school district’s records office, the examiner called the teacher, who emailed the IEP within two days. The claim was approved 41 days after filing, well below the national average processing time of 184 days for childhood SSI claims in fiscal year 2025.
Section 3 – Information About the Child’s Illnesses, Injuries, or Conditions
This is the heart of the form. List every physical, mental, learning, behavioral, or developmental condition. Do not limit yourself to the “main” diagnosis. If the child has autism, anxiety, eczema, and asthma, list all four. SSA must consider the combined effect of all impairments under 20 C.F.R. § 416.923.
For each condition, give the date it began limiting the child’s activities. If you do not know the exact date, write “approximately” and the month and year. Then explain in plain words how each condition limits the child. “Asthma” is not enough. “Asthma, hospitalized 3 times in 2025, uses albuterol nebulizer 4x daily, cannot run more than 30 seconds without wheezing” is the level DDS needs to evaluate against Listing 103.03 (asthma).
The misconception here is that “more conditions look like exaggeration.” The opposite is true. Combined impairments often push borderline claims over the line. The consequence of listing only one condition is that DDS scores only one condition.
Section 4 – Information About the Child’s Medical Treatment
Section 4 is where claims live or die on completeness. List every doctor, clinic, hospital, emergency room, therapist, psychologist, psychiatrist, and specialist the child has seen in the past 12 months, plus any earlier providers who treated the listed conditions.
For each provider, give the full name, complete street address, phone number, dates of first and most recent visit, reasons for visits, and any tests performed. If the child saw a school-based speech therapist, list the school. If the child went to urgent care once, list it. DDS will fax records requests to every provider listed under 20 C.F.R. § 416.912(b)(1).
Section 4 (continued) – Medications
List every prescription and over-the-counter medication the child takes regularly, the dose, who prescribes it, and the reason. Side effects matter. If Adderall causes appetite loss and insomnia, write that. Side effects feed the health and physical well-being domain under § 416.926a.
A real example: Aisha Brooks, age 9, takes guanfacine 2 mg at bedtime for ADHD, fluticasone inhaler 110 mcg twice daily for asthma, and melatonin 3 mg for sleep. Her mother listed all three with prescribing doctors. DDS used the medication list to confirm ongoing treatment severity, and the claim was approved at the initial level.
Section 4 (continued) – Tests
List every test the child has had or is scheduled to have, including the type, date, and where it was done. Common tests for childhood SSI include EEG, MRI, CT, X-ray, blood work, hearing and vision tests, IQ testing, and psychological evaluations. If a private psychologist did a WISC-V or WPPSI-IV, list it. SSA gives strong weight to standardized cognitive testing under Listing 112.05 (intellectual disorder).
Section 5 – Education
Section 5 asks about the highest grade completed, current grade, school name and address, special education status, and any IEP or 504 plan. If the child has an IEP, attach the most recent one. If the child is not yet in school, describe early intervention services under Part C of IDEA.
This section also asks if the child has ever been in special classes. Answer yes if the child has any pull-out service, including speech therapy, occupational therapy, or resource room. The consequence of saying “no” when the child does receive services is that DDS misses powerful evidence of functional limitation.
Section 6 – Remarks
Use the remarks page generously. This is where you continue any answer that ran out of space and where you tell the child’s story. Describe a typical day from wake-up to bedtime. Describe what the child cannot do that same-age peers can do. Describe what happens during a meltdown, seizure, or asthma attack. Describe how long it takes the child to dress, eat, or fall asleep.
The misconception is that remarks are optional. They are not. A blank remarks page is a missed chance to put the child’s functioning in front of the examiner in the parent’s own voice.
Three Common Scenarios With Filing Outcomes
Each scenario below shows a typical fact pattern and the most likely DDS outcome based on how the SSA-3820-BK is completed.
| How the Form Is Completed | What DDS Does Next |
|---|---|
| Parent lists “autism” only, no providers, no IEP attached | Sends consultative exam request, likely denial for insufficient evidence under 20 C.F.R. § 416.918 |
| Parent lists autism, ABA therapist, developmental pediatrician, IEP, two ER visits for elopement | Requests records, often approves under Listing 112.10 without consultative exam |
| Parent lists autism plus anxiety plus eczema, full provider list, daily-life narrative in remarks | Approves at initial level or schedules teacher questionnaire to confirm marked limitation in two domains |
| Type of Impairment Described | Likely Functional Domain Score |
|---|---|
| “ADHD, can’t sit still” with no detail | No marked limitation found |
| “ADHD, fails to complete 90% of assigned work, 3 office referrals per week, IEP goal at 20% mastery” | Marked in attending and completing tasks |
| “ADHD plus oppositional defiant disorder, suspended 12 days this year, no friends, hits sibling daily” | Marked in attending tasks and interacting with others, often equals listing |
| How Treatment Is Listed | DDS Record Development |
|---|---|
| “Dr. Smith” with no address | Records not requested, denial likely |
| “Dr. Anita Smith, 123 Main St, Cleveland OH 44101, 216-555-0100, since 2023” | Records faxed within 5 business days |
| Full provider list plus signed Form SSA-827 | Complete record built within 30 days |
Named Examples You Can Model
Diego Lopez, age 4, has autism spectrum disorder, level 3, and global developmental delay. His mother Maria listed his developmental pediatrician at Cleveland Clinic, his ABA provider, his speech therapist, and his Part C early intervention coordinator. In remarks, she wrote that Diego is nonverbal, bites his hands when overstimulated, cannot use a spoon, and requires constant supervision. DDS approved at the initial level under Listing 112.10.
Aisha Brooks, age 9, has ADHD combined type and moderate persistent asthma. Her father listed her pediatrician, her psychiatrist, three asthma-related ER visits in 2025, her current medications, and her 504 plan. He attached a teacher questionnaire showing she completes 30% of in-class work and needs prompts every 5 minutes. DDS found marked limitation in attending and completing tasks and approved the claim.
Marcus Johnson, age 12, has spastic diplegic cerebral palsy. His grandmother, his legal guardian, listed his neurologist, orthopedic surgeon, physical therapist, occupational therapist, and the local children’s hospital where he had selective dorsal rhizotomy in 2024. She attached his IEP showing he uses a walker and a Functional Mobility Scale score of 3. DDS approved under Listing 111.07 (cerebral palsy).
Mistakes to Avoid on Form SSA-3820-BK
- Listing only the primary diagnosis. The negative outcome is that DDS scores only that condition and ignores the combined effect required by 20 C.F.R. § 416.923.
- Writing “N/A” or leaving blanks. The negative outcome is that DDS interprets blanks as “no limitation” and the claim weakens.
- Giving incomplete provider addresses. The negative outcome is that records are never requested and the file is decided on the consultative exam alone.
- Forgetting to sign Form SSA-827, the medical release. The negative outcome is that no provider can release records to SSA, and the claim sits idle.
- Skipping the school section because the child is “too young.” The negative outcome is that early intervention evidence under IDEA Part C never enters the file.
- Using medical jargon the parent does not understand. The negative outcome is that contradictions appear when DDS calls to clarify and the parent cannot explain.
- Leaving the remarks page blank. The negative outcome is that the examiner never hears the child’s daily story in the parent’s own words.
- Failing to update the form after new diagnoses. The negative outcome is that newly diagnosed conditions are not considered until appeal.
- Listing the child’s age but not height and weight. The negative outcome is that growth-based listings cannot be evaluated.
- Filing without an IEP or report card attached. The negative outcome is that DDS waits weeks for school records that the parent already had at home.
Dos and Don’ts
- Do answer every single question, even with “none” or “unknown.” Blanks are interpreted against the claim.
- Do attach the IEP, 504 plan, and recent report cards. They are the strongest free evidence available.
- Do use the remarks page to describe a typical day. Functioning narratives drive § 416.926a domain scoring.
- Do list every provider, even one-time ER visits. Combined records often reveal patterns.
- Do keep a copy of the completed form. You will need it for the reconsideration appeal under 20 C.F.R. § 416.1407.
- Don’t exaggerate. False statements violate 20 C.F.R. § 416.1011 and can trigger fraud penalties.
- Don’t use vague phrases like “always” or “never” without examples. DDS examiners discount unsupported absolutes.
- Don’t wait to file because records are missing. SSA helps gather records once the form is in.
- Don’t sign the form on behalf of someone else without authority on file. Improper signatures void the protective filing date.
- Don’t skip Part B of the Listing of Impairments when describing conditions. Childhood listings are different from adult listings.
Pros and Cons of Filing on Paper vs. Online
| Filing Method | Why It Helps |
|---|---|
| Paper SSA-3820-BK | Lets you photocopy and edit before mailing, preserves a physical record, easy to attach IEP and reports |
| Online i3820 | Auto-saves progress, prevents skipped questions, faster transmission to DDS, immediate confirmation number |
| Phone interview with field office | Field office staff complete the form with you, useful for parents with literacy or language barriers |
| Filing Method | Where It Hurts |
|---|---|
| Paper SSA-3820-BK | Slower mail handling, risk of lost pages, no auto-save if you stop midway |
| Online i3820 | Session timeouts can erase work, attachments must be uploaded separately, requires stable internet |
| Phone interview | Limited time, parent may forget conditions on the spot, fewer chances to expand on remarks |
State Nuances You Should Know
Although the SSA-3820-BK is federal, the state DDS agency actually decides the medical merits. Each state’s DDS sets its own internal triage. California’s DDS, the largest in the country, uses an electronic case analysis tool that flags incomplete provider lists for return without development. Texas DDS routinely orders a consultative exam when fewer than two treating sources are listed. New York DDS gives heavy weight to school records and often defers a decision until the IEP arrives.
The plain-English consequence is that the same SSA-3820-BK can move faster or slower depending on the state. The misconception is that federal SSI is uniform at every step. It is uniform in standard, not in processing. A real example: Priya Shah filed her daughter’s claim in Florida and Illinois at different times. The Florida DDS approved in 47 days because the file was complete. The Illinois DDS took 162 days on a later, similar claim because two provider addresses were wrong.
State Medicaid status also matters. In most states, an SSI approval automatically grants Medicaid. In the 209(b) states, which include Connecticut, Hawaii, Illinois, Minnesota, Missouri, New Hampshire, North Dakota, Ohio, Oklahoma, and Virginia, families must file a separate Medicaid application even after SSI approval.
After You Submit: What Happens Next
Once SSA receives the SSA-3820-BK, the field office attaches it to the SSA-8000-BK financial application and the SSA-827 medical release, then forwards the file to the state DDS. A disability examiner is assigned, usually within two weeks. The examiner orders records, may send a Teacher Questionnaire (Form SSA-5665-BK) to the school, and may schedule a consultative exam if records are thin.
If the claim is denied at the initial level, you have 60 days to request reconsideration under 20 C.F.R. § 416.1409. After reconsideration, you can request a hearing before an administrative law judge under 20 C.F.R. § 416.1429. The hearing-level approval rate for childhood SSI in fiscal year 2025 was about 47%, far higher than the initial-level rate.
The misconception is that a denial means the case is over. It does not. Most childhood SSI approvals happen on appeal, and the SSA-3820-BK you filed at the start travels with the case through every level. That is why accuracy at the start saves months later.
Key Entities You Will Encounter
The Social Security Administration (SSA) is the federal agency that runs the SSI program. The state Disability Determination Services (DDS) makes the medical decision under federal rules. The Office of Hearings Operations (OHO) handles administrative law judge hearings. The Appeals Council reviews ALJ decisions. Federal district courts review final agency decisions under 42 U.S.C. § 405(g).
Each entity uses the SSA-3820-BK as the foundational medical document. The form follows the case from the field office to DDS to OHO to the Appeals Council to federal court. Inconsistent answers on the form can be cross-examined years later, which is why every word should be accurate, complete, and in the parent’s own voice.
Recap of Relevant Rulings
In Sullivan v. Zebley, 493 U.S. 521 (1990), the Supreme Court struck down SSA’s old listings-only test for children and required individualized functional analysis. That ruling created the framework now codified at 20 C.F.R. § 416.926a. The consequence for the SSA-3820-BK is the entire functional narrative section of the form.
In Encarnacion ex rel. George v. Astrue, 568 F.3d 72 (2d Cir. 2009), the Second Circuit upheld SSA’s six-domain framework against challenge, confirming that “marked” limitation in two domains or “extreme” in one equals disability. The consequence is that parents should write answers that map to two domains at minimum.
In Briscoe ex rel. Taylor v. Barnhart, 425 F.3d 345 (7th Cir. 2005), the Seventh Circuit reversed a denial because the ALJ ignored teacher evidence. The consequence is that school evidence carries real weight, and Section 5 of the SSA-3820-BK should never be skipped.
Frequently Asked Questions
Is Form SSA-3820-BK only for SSI claims?
Yes. The form is used for childhood SSI claims under Title XVI. Title II childhood disability benefits for adult children disabled before 22 use Form SSA-3368-BK instead.
Can I file Form SSA-3820-BK online?
Yes. SSA’s online Child Disability Report (i3820) is the electronic version and is generally faster and cleaner than paper.
Do I have to attach the IEP?
No. Attachment is not legally required, but skipping it weakens the claim. School evidence is one of the strongest non-medical proofs of functional limitation under § 416.926a.
Can a non-parent fill out the form?
Yes. Legal guardians, foster parents in many states, and appointed representatives under SSA-1696 may complete and sign the form for the child.
Does the form ask about household income?
No. Income and resources go on the SSA-8000-BK. The SSA-3820-BK is medical and functional only.
Will SSA pay for a consultative exam if I list no doctors?
Yes. SSA will schedule one under 20 C.F.R. § 416.917, but a single exam rarely supports approval without treating-source records.
Can I update the form after I file?
Yes. Submit a new SSA-3820-BK or written statement to the DDS examiner any time before the decision. Updates also go on Form SSA-3441 at appeal.
Does autism alone qualify?
No. Autism must cause marked and severe functional limitations under Listing 112.10. Diagnosis alone never wins; functioning does.
Is there a deadline to file?
No. SSI has no filing deadline, but benefits start the month after the application date, so delay costs money.
Can I get back pay before the application date?
No. Unlike SSDI, SSI pays no retroactive benefits before the application month under 20 C.F.R. § 416.501.
Do I need a lawyer to fill out the form?
No. Many parents file successfully without counsel. A representative helps most when the case is complex or already denied.
What if my child turns 18 during the claim?
Yes, SSA performs an age-18 redetermination under adult rules within one year of the 18th birthday. File a new adult disability report at that point.
