The purposes of this study were to: 1) create and develop effective doctoral learning module on leading teachers development program to enhance critical thinking for students in secondary schools under the Office of Basic Education Commission, and 2) evaluate the developed module on its efficiency and effectiveness- its congruence of utility, possibility, and appropriateness, learning achievement of learners, learning retention, and the learners’ satisfaction. Samples were 20 Doctoral degree students in Educational Administration and Development and Leadership program, Northeastern University, Khon Kaen Province, Thailand. Statistics used were percentage, mean, standard deviation, effectiveness index, and t-test.
