The supply of traditional school of education graduates must be augmented to meet the demand for science and mathematics teachers. This report examines recent programmatic responses to breaking down institutional barriers. In most instances examined, special programs were designed to prepare mathematics and science teachers, and each program was targeted on a specific population such as retired persons, persons changing careers, or recent college graduates. The problems identified underscore the need to move teacher education to the graduate level. Descriptions are given of a number of special teacher preparation programs which are classified into three categories: (1) nontraditional recruitment programs which provide potential teachers from nontraditional pools with course work and other requirements for certification in mathematics or science; (2) alternative certification programs, designed to prepare teachers to meet revised state certification requirements for entering teaching; and (3) retraining programs, designed to help teachers already trained in other fields to obtain endorsement or certification in mathematics or science.
