Pearson sought to explore whether the students in schools in Brazil using the NAME learning system (an integrated program that encompasses a school's whole educational environment) demonstrate higher achievement in Portuguese and math, compared to those not exposed to NAME, as measured by national achievement assessments. This Research Report presents findings from one research study: a quasi-experimental study comparing 54 schools using NAME with 267 comparable non-NAME schools. A comparative study design was chosen to seek out possible relationships between exposure to NAME and students' achievement, to identify areas of focus for potential future research using more rigorous causal study designs. The findings appear alongside details of the research study, including a description of the sample studied, method of analysis, results, limitations and generalizability, and notes on possible future research. The report also summarizes the context surrounding the findings, including the research that informed the design and development of the product, the history of the product in the market, how educators use the product, and its intended outcomes.
