Evaluation of Teachers Trained Through Different Routes to
Evaluation of Teachers Trained Through Different Routes to Certification Presentation at the IES Research Conference June 2009 Jill Constantine Mathematica Policy Research, Inc. Motivation Alternative certification (AC) programs supply increasing numbers of teachers Debates on whether AC programs adequately prepare teachers for the classroom The effectiveness of different training strategies has not been rigorously studied
What are AC Programs? Allow teachers to begin teaching before completing required coursework Typically require less coursework than traditional certification (TC) programs and no student teaching Have perceived advantages and disadvantages Reduce barriers to entry (positive) Produce teachers with inadequate training (negative) Previous Research Numerous rigorous studies on selective AC programs, but are mainly about TFA and NYC Teaching Fellows
Most AC programs are not highly selective with admission requirements similar to TC programs Study expands evidence on AC teachers by examining teachers from less selective programs in 7 states Research Questions 1. What are the effects on student achievement of teachers trained through different routes to certification? 2. What aspects of teacher preparation are associated with teacher effectiveness?
Amount of coursework Timing of coursework Content of coursework Study Design Research Design and Participants: Randomly assign students to novice AC or TC teacher in the same grade and school to create several miniexperiments Analysis: Compare outcomes of students randomly assigned to AC teacher to those randomly assigned to TC teacher Study design: Provides a test of the effectiveness of teachers from different preparation programs, not direct test of the programs Selecting AC Programs Focused on less-selective programs, admissions requirements similar to TC programs

No other subgroups showed statistically significant differences Teacher Practices Non-Experimental Results Differences in AC teachers' characteristics, practices, and training explained about 5 percent of math scores and 1 percent of reading scores Students of AC teachers taking coursework scored lower than TC comparisons in reading Students of AC teachers with master's degrees scored lower than TC comparisons in reading
No other differences were statistically significant Summary Students of AC teachers performed the same, on average, as students of TC teachers in their schools Variation in the amount and content of required coursework in teacher preparation was not linked to teachers' effectiveness in terms of student achievement Completing required coursework while teaching is associated with lower student achievement
