The purpose of the study was to develop a "Test Preparation and Test Taking Strategies Scale" (TPTTS) to diagnose exam-preparation and exam-taking strategies to be used by students preparing for the university selection examinations at national level. The participants of the study were from different kinds of public high schools and were preparing for the university entrance exam in a private training center located in Bolu, Turkey. To detect the construct validity of TPTTS, Exploratory Factor Analysis procedure was applied with varimax rotation. First of all, the scale was prepared as two main scales: (1) Test Preparation and (2) Test Taking Strategy having a total of 37 items. The first part of the scale "Test Preparation Strategies" consists of three sub-scales which are cognitive strategies (7 items), social strategies (3 items) and metacognitive strategies (7 items). The second part of the scale "Test Taking Strategy" consists of four subscales which are item analysis strategies (7 items), time management strategies (4 items), choice prediction strategies (3 items) and after test strategies (3 items). The internal consistency coefficients of the subscales change from 0.39 to 0.78 depending on the number of items.
