From a teacher quality perspective—and supporting NCTQ's contention for broad-based, respectable, and widely-offered programs—there exists substantial research demonstrating the need for states to adopt alternate certification programs. Independent research on candidates who earned certification through the alternate-route Teach For America (conducted by Kane, Parsons and Associates) and the American Board for Certification of Teacher Excellence (conducted by Mathematica Policy Research, Inc. and ABCTE) programs has found that alternate route teachers are often as effective, and, in many cases, more effective, than traditionally-prepared teachers.

Specifically, evidence of the effectiveness of candidates in respectable and selective alternate certification requirements can be found in J. Constantine, D. Player, T. Silva, K. Hallgren, M. Grider, and J. Deke, An Evaluation of Teachers Trained Through Different Routes to Certification, Final Report.

A number of studies have also found alternative-certification programs such as Teach for America to produce teachers that were more effective at improving student achievement than other teachers with similar levels of experience.
