This review article reports, citing Darling-Hammond (2000), a state-level analysis of six NAEP state assessments. The printed correlations between percent uncertified new teachers and performance "ran from –.40 to –.63," correlation values at or above r = .37, coded as large impact.
"she found the percent of new teachers in a state who were uncertified correlated negatively with performance on six different state assessments conducted by the National Assessment of Educational Progress. These correlations ran from –.40 to –.63."
