To qualify for employment under Schedule A, a person must have the following:

Proof of Disability: An individual wishing to be hired under the Schedule A (5 C.F.R.213.3102(u)) hiring authority must provide proof he or she is an individual with mental retardation, severe physical disability, or psychiatric disability. This proof must be provided to the hiring agency before an individual can be hired.

Certification of Job Readiness: An individual hired under this authority must be ready to perform the job for which they are being considered. This certification is a statement that the individual is likely to succeed in the performance of the duties of the position for which he or she is applying. As proof of disability and certification of job readiness appropriate documentation can be records, statements, or other appropriate information issued from a licensed medical professional, a licensed vocational rehabilitation specialist, or any federal agency, State agency, or a U.S. territory that issues or provides disability benefits.

Temporary Appointments: Temporary appointments may be considered for individuals who have proof of disability but lack certification of job readiness. Individuals may work under the temporary appointment until the agency determines that the individuals are able to perform the duties of the position, or the individuals gain certification. Time-limited appointments may be considered when the duties of the position do not require it to be filled on a permanent basis. 

The U.S. Department of Commerce provides reasonable accommodations so that people with disabilities have the opportunity to perform the duties of their positions.
