This article investigates the relationship between the structural features of middle grades teacher preparation programs (TPPs) and student achievement gains in math and English/Language Arts (ELA), focusing on teachers recommended for initial licensure, prepared in University of North Carolina (UNC) system institutions. The findings reveal that subject matter has a negative relationship to middle grades mathematics achievement but no relationship to student achievement for ELA. Further, there is a negative relationship of full-time student teaching responsibility for mathematics and no relationship for ELA. Similarly, there is evidence of a negative relationship of early fieldwork hours to mathematics achievement, but no relationship to ELA achievement.
