Four nontraditional teacher education programs to attract and train mathematics and science teachers are described. Three of the programs are aimed at midcareer professionals; the fourth is aimed at recent college graduates who did not prepare to become teachers as undergraduates. All are small programs; they provide models for other institutions to follow. The programs are at Harvard University, the University of Massachusetts, the University of Vermont, and Washington University in St. Louis, Missouri. The study was organized around six research questions: (1) What are the characteristics of these programs? (2) What are the characteristics of their students? (3) What attracted the students to the programs? (4) What are students' evaluations of the programs? (5) What are the career plans and motivations of the students? and (6) What are the recommendations of the students for program design? After the six questions are answered, conclusions and recommendations are presented and five suggestions for further research are given. (MNS)
