I am looking for a literature review chapter to support (or that could be used to refine) the following research questions. This is for my master thesis. The literature review would focus primarily on defining what good psychometric properties would be of a literacy assessment generally and an Early Grade Reading Assessment (EGRA) specifically, as well as the socio-contextual factors most likely to impact literacy outcomes. While this could focus on these themes globally, it would be ideal to focus on Subsaharan Africa or LMIC specifically for sources. The number of sources is flexible based on what is available. Draft Research Questions: 1. Do the items from the 2019 Grade 2 Sierra Leone EGRA show good psychometric properties, including targeting, uni-dimentionality, reliability, and lack of differential item functioning, etc. 2. To what extent can the CRS McGovern-Dole Grade 2 Sierra Leone EGRA results be mapped into curriculum-aligned performance bands? 3. What social-contextual factors predict students’ likelihood to appear in the highest and lowest performance bands? a. What is the most predictive social-contextual factor of their literacy skills attainment? b. Are the social-contextual factors’ associations with literacy skills attainment the same for girls and boys? c. Are the social-contextual factors’ associations with literacy skills attainment the same across all districts?
