A social security disability hearing is held to determine if an individual meets the requirements for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) benefits. During the hearing, the administrative law judge will consider several types of evidence to determine the individual's eligibility for benefits. The following are some of the types of information that may be needed at a Social Security disability hearing:

1. Medical Records: Medical records are one of the most critical pieces of evidence in a disability hearing. The judge will want to review all medical records related to the individual's condition, including hospital records, doctor's notes, lab test results, and any other medical documentation that may be relevant.

2. Vocational Evidence: The judge will consider the individual's work history and educational background to determine if they are capable of performing any type of gainful employment. This may include vocational expert testimony, which is an evaluation of the individual's abilities and limitations.

3. Witness Testimony: The judge may consider testimony from witnesses, such as family members, friends, or coworkers, who can provide information about the individual's condition and limitations.

4. Function Reports: Function reports are forms completed by the individual and their family members or caregivers that provide details about the individual's daily activities, such as their ability to perform self-care tasks, complete household chores, or participate in social activities.

5. Any other relevant information: The judge may consider any other relevant information related to the individual's disability, such as school records or other types of documentation that support the claim.

It's important to note that the evidence needed may vary depending on the specific case, and the judge may request additional information as needed. It's always a good idea to work with an experienced Social Security disability representative to ensure that all necessary evidence is provided and presented effectively during the hearing.
