This document presents the revised Annual Evaluation Plan for fiscal year 2025 for the U.S. Department of Housing and Urban Development (HUD or the “Department”). HUD publishes an Annual Evaluation Plan (AEP) each year to document the major evaluation activities it plans to undertake in that fiscal year. Significant evaluation activities are those that meet defined criteria for topical relevance, coordination, and commitment of resources. The AEP describes the new significant evaluation activities the Department plans to undertake in the fiscal year and lists the significant evaluation activities that are already underway and will continue through the fiscal year. The remainder of this introduction provides background on HUD’s evaluation activities and how the AEP relates to HUD’s Strategic Plan and Learning Agenda.
