How to Fill Out and Submit the Child Disability Report (SSA-3820-BK)

SSA Form SSA-3820-BK is the Child Disability Report the Social Security Administration uses to gather the medical, educational, and functional evidence it needs to evaluate a child’s Supplemental Security Income claim.¹ To fill it out well, pull together every provider, school, and program that has seen the child, then write descriptions specific enough that an adjudicator can picture exactly how the condition affects daily life. To submit it, complete it online and wait for SSA to call you, or bring or mail the paper version to your local field office.

The form itself does not decide the claim. It tells SSA where to request records and paints a picture of the child’s functioning. Gaps here become delays or denials later.

What This Form Covers and What It Doesn’t

The SSA-3820-BK is only the medical and functional side of a child’s SSI claim. SSA runs a separate application covering household income, resources, and living arrangements. After you finish the Child Disability Report, an SSA representative contacts you to review the medical information and start the broader SSI application.² You will also sign Form SSA-827, which authorizes SSA to obtain records from the providers you list.

Federal law defines childhood disability for SSI as a medically determinable physical or mental impairment causing marked and severe functional limitations that has lasted, or is expected to last, at least 12 continuous months or result in death.³ A child earning above the 2026 substantial gainful activity threshold of $1,690 per month cannot qualify regardless of condition severity.⁴

What to Gather Before You Start

The form runs roughly 14 pages across ten sections. Almost every section asks for names, addresses, phone numbers, and dates you probably don’t have memorized. Pulling records together first keeps you from setting the form aside halfway through.

Medical Records and Provider Details

Collect the full name, address, phone number, and patient ID for every doctor, therapist, hospital, clinic, or mental health professional who has treated the child. The form asks for specific visit dates and treatments, so appointment summaries or patient-portal printouts help. List every current medication with dosage, prescribing doctor, reason, and side effects. Note emergency room visits and hospitalizations with facility name and dates. Section 6 asks about medical tests such as EKGs, blood work, hearing or vision tests, and IQ or psychological evaluations, including where and when they were done.¹

Educational Records

Section 8 asks for current and former schools, teacher names, and whether the child has been tested for behavioral or learning problems. If the child has an Individualized Education Program, bring a copy. The form specifically instructs you to send it along or bring it to your interview.¹ Speech or language therapy records, special education placement letters, and results of any school psychological testing are worth having on hand.

Other Sources Who Know the Child

Section 7 asks whether Head Start, a public health department, or an early intervention program has tested or examined the child. Have that contact information ready. Also note anyone outside the medical and school systems who can describe how the condition shows up day to day: a daycare provider, a family member, a coach. SSA sometimes reaches out for third-party statements.

Filling Out the Form Section by Section

You can complete the form online through SSA’s website or download the PDF and fill it in by hand.²

Sections 1 and 2: Child and Contact Information

Section 1 covers the child’s name, Social Security number, date of birth, height, weight, language spoken at home, living arrangements, and whether the child has a medical assistance card like Medicaid. Section 2 collects information on legal guardians, custodians, or other adults involved in the child’s daily care. If someone other than a parent handles medical appointments or school meetings, list them.¹

Section 3: Conditions and Their Effects

This is where many applicants are too vague and pay for it later. List every illness, injury, or condition; the approximate date the disability began; and whether the child experiences pain or other symptoms. Do not write only a diagnosis name like “ADHD” or “cerebral palsy.” Describe what the condition actually does. Something like: “Diagnosed ADHD-combined type. Cannot sit through a 20-minute meal without leaving the table. Removed from classroom twice a week for disruptive behavior. Needs one-on-one redirection to complete a single homework page.” Concrete pictures leave less guesswork for the adjudicator.

Section 4: Medical Records

This section runs several pages and asks for provider name, address, phone, patient ID, visit dates, and what the child was treated for. Separate blocks cover doctors, hospitals, and other sources such as school nurses or social workers. Fill in every provider, even ones the child saw only once. SSA requests records from each source you list, and a single omission can leave a gap that reads as a milder condition than the child actually has.¹

Sections 5 and 6: Medications and Tests

List every current medication with dosage, prescribing doctor, reason, and side effects. Side effects matter more than most people realize. If a medication makes the child drowsy, nauseous, or unable to concentrate, that context shapes how the child functions through the school day. Section 6 covers medical tests already done or scheduled, including imaging, bloodwork, psychological evaluations, and hearing or vision testing. Include the facility name and date for each.

Section 8: Education

List the current school, grade level, and teacher names. Indicate whether the child attends special education classes, has repeated a grade, or receives services like speech therapy or occupational therapy. Note any IEP or Section 504 plan. This is also where you document daycare or preschool attendance for younger children. School records are a major source of evidence for childhood claims because they show how the child functions compared to same-age peers day after day.

Sections 9 and 10: Work History and Remarks

Section 9 asks whether the child has any work history, including sheltered employment. Most young children have nothing to enter. For teenagers this matters: earned income above $1,690 per month can disqualify the claim entirely.⁴ Section 10 is a remarks section, and it is your best friend on this form. Use the extra space for a timeline of hospitalizations, a summary of how the condition has worsened, or anything an adjudicator should know that did not fit the structured fields.

Write Descriptions That Match the Six Functional Domains

SSA evaluates childhood disability by measuring how a child functions compared to same-age peers across six domains. Even if the condition doesn’t meet a specific listing in SSA’s Listing of Impairments, the claim can succeed if the evidence shows “marked” limitations in two domains or an “extreme” limitation in one.⁵ Writing your Section 3 and Section 10 descriptions with these categories in mind maps your information directly onto how the case gets decided.

Acquiring and using information: whether the child learns new things, understands instructions, and applies what they’ve learned. A 10-year-old who can’t read at a first-grade level or follow two-step directions shows a limitation here.
Attending and completing tasks: whether the child can focus, work at a reasonable pace, and finish activities without constant redirection.
Interacting and relating with others: whether the child initiates and maintains relationships, cooperates with adults, and responds to social cues.
Moving about and manipulating objects: whether the child walks, runs, climbs, and uses hands and fingers in ways expected for their age.
Caring for yourself: whether the child handles dressing, bathing, and feeding, recognizes danger, and regulates emotions.
Health and physical well-being: how often the condition causes episodes of illness, exacerbations, or ongoing treatment that disrupts the child’s routine.

Tie your descriptions to these categories. Instead of “he has trouble at school,” write “he cannot stay focused on a single worksheet for more than three minutes without an aide tapping his desk (attending and completing tasks), and he hits other children during recess when they won’t play the game he wants (interacting with others).” That specificity is what moves a claim forward.

How to Submit the Completed Form

You have three options, and none is a self-service upload portal that spits out a confirmation number. The process runs through a person.

Online

Complete the Child Disability Report on SSA’s website. After you finish, an SSA representative contacts you to go over the medical information, verify income and resource eligibility, and begin the formal SSI application.² This is the fastest way to start because SSA has the data as soon as you submit.

In Person at a Field Office

If you have an in-office interview, bring the completed paper form. Staff can review it on the spot, and you can hand over copies of IEPs, medical records, and test results at the same appointment. Ask for a date-stamped receipt confirming delivery.¹

By Mail

Mail the completed form to your local SSA field office. Send it certified with return receipt requested so you have proof of delivery. Make sure every page is included and Section 10 is dated. Keep a full photocopy of everything you send.

What Happens After You Submit

Once SSA’s field office confirms non-medical eligibility (age, income, resources), it forwards the case to your state’s Disability Determination Services office for medical evaluation.⁶ DDS adjudicators and medical consultants review your form answers, records from every provider you listed, school records, and any third-party statements. The initial decision generally takes three to six months. Complex cases or difficulty obtaining records can push it longer.

If DDS cannot decide on the records alone, it schedules a consultative examination with a medical professional.⁷ SSA pays for the appointment and related travel.⁸ The examiner runs only the specific tests DDS requested; they do not prescribe treatment and do not decide the claim. DDS prefers to use the child’s own treating doctor when practical. If you get a scheduling letter, keep the appointment. Missing it without rescheduling can stall or sink the case.

If the Claim Is Denied

Denial rates for childhood SSI claims are high, and a denial isn’t the end of the case. You have 60 days from the date you receive the decision notice to request reconsideration.⁹ SSA presumes you received the notice five days after mailing, so the working deadline is 65 days from the mailing date. A late request is possible on a showing of good cause, such as serious illness or never receiving the notice, but don’t rely on it.¹⁰

At reconsideration, a different examiner at DDS reviews the entire file along with new evidence you submit.⁹ This is your opportunity to fill whatever gap led to the denial: a missing specialist report, updated test scores, a teacher’s statement you didn’t include the first time. If reconsideration is also denied, the next step is a hearing before an administrative law judge. The 60-day deadline applies at each level.
