Regardless if you have applied for Social Security Disability Insurance Benefits (SSDI) or Supplemental Security Insurance Benefits (SSI), the Social Security Administration uses a 5-Step sequential evaluation process to determine if an individual is disabled. If the proof fails at any Step, except Step-3, a finding not disabled will be issued.

An individual has the burden to establish that the individual cannot perform the work the individual has performed (as defined in the Dictionary of Occupational Titles) in the last 15 years.
