The 3 x 2 Student Achievement Goal Orientation Inventory was designed with a series of items adapted from Elliot, Murayama, & Pekrun (2011). Items were designed to assess dimensions of achievement goals (task, self, and other). The current study evaluated and compared four models: (a) 1 x 2 factor model, (b) 2 x 2 factor model, and (c) 3 x 2 factor model. American high school students (N = 261) were surveyed and confirmatory factor analysis performed. Results indicate the 3 x 2 factor model was confirmed as the best fitting model. Modification and fit indices, limitations, and applications are discussed.
