This report presents a summary of the findings of fiscal year (FY) 2018 Head Start monitoring reviews, fulfilling the reporting requirement in Section 641A(f) of the Head Start Act. It highlights the enhancements made to the FY 2018 monitoring review system, summarizes grantee review outcomes, and describes the types of findings most commonly identified in FY 2018. In September 2016, the Office of Head Start (OHS) issued the first holistic revision and complete reorganization of the Head Start Program Performance Standards (HSPPS) since their original publication in 1975. OHS significantly modified the FY 2017 review schedule to provide opportunities for the Head Start community to implement the new HSPPS and for OHS to refine its system to monitor the new HSPPS. OHS implemented the new aligned monitoring system in FY 2018. The revised Aligned Monitoring System (AMS 2.0) was designed to monitor the newly implemented HSPPS, streamline the monitoring process, and reduce grantee burden of having multiple review events from multiple agencies. AMS 2.0 retained some components from its original design, including CLASS®, Special, and Follow-up reviews, which were implemented with procedures identical to those implemented in the original AMS. AMS 2.0 also introduced two new review types: Focus Area One and Focus Area Two. [For the 2017 report, see ED600423.]
