Assessing School Performance with Nevada's Growth Model of Achievement

Primary Researchers: Eric Crane, Loan Tran, Andrea Lash


In 2009, Nevada’s Assembly Bill 14 (NRS 385.3595) directed the Nevada Department of Education to adopt a growth model of student achievement that would evaluate a school’s progress by tracking the achievement of its students from year to year (Nevada Assembly Bill 14, 2009). During 2009 and 2010, the Nevada Growth Model of Achievement (NGMA) was selected and piloted. Beginning in 2011, the model was to be introduced and made operational throughout Nevada’s 17 school districts. Measures of schools’ progress as derived from the NGMA will be reported annually, in math and reading, for grades 4 through 8. The growth scores will be derived from student scores on the state’s criterion referenced tests that are used for accountability purposes to evaluate whether schools meet adequate yearly progress in accordance with the No Child Left Behind Act (Nevada Department of Education, 2010). 

As they prepared to introduce the Nevada Growth Model for Achievement, senior leaders at the Nevada Department of Education anticipated they would receive questions about the NGMA measures of school performance, so they asked REL West for assistance in conducting analyses of school-level performance measures to address these questions.
