The purpose of this study was to examine the role of school background and school process in closing achievement gaps between White and non-White students in science. To answer the research questions, a series of two-level hierarchical linear models (HLM) was performed on the fourth-grade U.S. portion of the 2015 Trends in International Mathematics and Science Study (TIMSS) data. Results indicate that (a) the science achievement gap between White and non-White students is 0.21 standard deviation, holding student and school background constant; (b) the science achievement gap varies across schools; (c) none of the school background variables are associated with the achievement gap in a school; and (d) school emphasis on student academic learning is not only associated with higher school-level science achievement, but also with a narrower science achievement gap between White and non-White students. However, teacher collaboration is not associated with school-level science achievement but is associated with a larger achievement gap. Implications, limitations, and recommendations for further research are discussed.
