The Tanzania National Early Grade Reading Assessment (EGRA) aims to gather data about the progress of Standard 2 students against the national benchmarks developed and adopted in 2014 and to collect contextual information about the implementation of the 3Rs (reading, writing, and arithmetic) reforms for early grade teachers in Tanzania. The pilot study is an important part of the life cycle of the study because the information collected helps us improve several aspects of our data collection for the full survey. This report will provide an introduction to the pilot study, describe the analyses conducted, discuss quality control measures implemented during the pilot, and explain how the assessment instruments were finalized based on the pilot study data.
