The Education Value-Added Assessment System (EVAAS), the value-added model (VAM) sold by the business analytics software company SAS Institute Inc., is advertised as offering "precise, reliable and unbiased results that go far beyond what other simplistic [value-added] models found in the market today can provide." In this study, we investigated these claims by conducting analyses on over 1,700 teachers' EVAAS results (i.e., actual EVAAS output to which no other external scholars have had access prior) from the Houston Independent School District (HISD). We found the EVAAS to perform, overall, in line with other VAMs in terms of validity and reliability, although it yielded possibly more biased value-added estimates than other VAMs. Hence, results do not support SAS's aforementioned claim.
