How many school psychologists are there in each country of the world? Findings from this study indicate over 76,100 school psychologists throughout 48 countries from which estimates were available as of 2007. When considering the total number of school psychologists in a given country, it is essential to also consider the number of school-age children. The school psychologist-to-student ratio provides an omnibus indicator of the development of the profession of school psychology in countries around the world. Calculations revealed a wide range of school psychologist-to-school-age children ratios in countries around the globe. It is notable that many of the countries with the largest populations of school-age children in the world have the fewest school psychologists. Ideas for future scholarship that will further enhance our understanding of school psychology internationally are discussed. (Contains 3 tables.)
