The Uzbekistan Education for Excellence Program(the Program) is a 4-year program (December 9, 2019–December 8, 2023) funded by the United States Agency for International Development (USAID) and implemented by the RTI International Consortium1 in collaboration with the Uzbekistan Ministry of Public Education. The Program conducted baseline Early Grade Reading and Mathematics Assessments (EGRA and EGMA, respectively) in November and December 2021. The purpose of the baseline was to measure the pre-intervention levels of mathematics and Uzbek language reading achievement for students at the end of grade 2 and grade 4. The baseline was originally planned to assess students completing grades 2 and 4 at the end of the 2019–2020 school year in May 2020. However, the baseline was postponed to the beginning of the following school year—November–December 2021—because of COVID-19, and grades 3 and 5 students were assessed as proxies for students completing grades 2 and 4, respectively.
