| Abstract: | Numerous studies cite a hypothesized relationship between teacher supply and certification standards in lieu of a relationship between teacher supply and teacher salaries. To date, no study has attempted to explore these relationships. This study examined these hypothesized relationships. The dependent variable was science teacher supply. The independent variables in this study were science teacher certification standards, reciprocity pacts, alternative certification, and teacher salary. Significant positive correlations were found between science teacher supply in one or more science subjects and (a) the existence of a broad field science endorsement, (b) the number of hours of science required for a broad field science endorsement, (c) the number of subjects covered by a broad field science endorsement, and (d) the number of states in a state's reciprocity pact. A significant negative correlation was found between science teacher supply and the existence of alternative certification. A significant negative correlation was found between salary index and teacher supply in several science subjects. Implications of these findings are discussed. © 1998 John Wiley & Sons, Inc.
