This study was designed to test validity and reliability of Academic Motivation Scale (AMS) for sports high school students. The research conducted with 357 volunteered girls (n=117) and boys (n=240). Confirmatory factor analysis showed that Chi square (χ2), degrees of freedom (df) and χ2/df ratio were 1102.90, 341 and 3.234, respectively. Goodness of Fit Index, Comparative Fit Index, Non-normed Fit Index and Incremental Fit Index were between 0.92-0.95. Additionally, Adjusted Goodness of Fit Index, An Average Errors Square Root and Root Mean Square Error of Approximation were 0.88, 0.070 and 0.079, respectively. Subscale reliability coefficients were between 0.77 and 0.86. Test-retest correlations of AMS were found between 0.79 and 0.91. Results showed that scale was suitable for determination of sports high school students’ academicals motivation levels.
