 The main objective of this compliance requirement is that only eligible individuals or organizations participate in federal assistance programs . While the criterion for determining eligibility may vary from program to program , the objective that only eligible individuals or organizations participate is consistent across all federal programs , which forms the basis of this compliance requirement . To comply with this objective , recipients must first assure that proper eligibility determinations are made , which means that the recipient must determine the parameters and limitations to define eligibility for a specific program in accordance with the program ’ s purpose . Many federal programs already contain eligibility requirements based on laws , agency regulations , grant agreements , etc . , and recipients must assure that their eligibility determination complies with such requirements . An example includes federal programs that offer HIV / Aids treatment and require that the participants be victims of such diseases . It is usually the recipient ’ s responsibility to determine how to determine such eligibility , such as establishing policy that requires an in @-@ house doctor or laboratory to diagnose each prospective participant , accepting diagnoses from third @-@ party doctors or laboratories , etc . However , certain agencies have included specific parameters for which the recipient should follow , as in the case of the Department of Housing and Urban Development ( HUD ) which states in the Code of Federal Regulations ( CFR ) that recipients of certain HUD housing subsidy programs must obtain specific income verification documents to prove participant eligibility , such as W @-@ 2 payroll forms , a federal income tax return , etc .
