45 CFR § 2522.710 - What are my evaluation requirements?
(a) If you are a State commission, you must establish and enforce evaluation requirements for your State formula subgrantees, as you deem appropriate.
(b) If you are a State competitive or direct Corporation AmeriCorps grantee (other than an Education Award Program grantee), and your average annual Corporation program grant is $500,000 or more, you must arrange for an independent evaluation of your program, and you must submit the evaluation with any application to the Corporation for competitive funds as required in § 2522.730 of this subpart.
(c) If you are a State competitive or direct Corporation AmeriCorps grantee whose average annual Corporation program grant is less than $500,000, or an Education Award Program grantee, you must conduct an internal evaluation of your program, and you must submit the evaluation with any application to the Corporation for competitive funds as required in § 2522.730 of this subpart.
(d) The Corporation may, in its discretion, supersede these requirements with an alternative evaluation approach, including one conducted by the Corporation at the national level.
