This study investigates the vocabulary learning strategies (VLSs) employed by 556 high school students to identify the most and least frequently used discovery and consolidation strategies. The study further investigates whether there is any difference between VLSs used with respect to gender, grade level, school type and age. To these ends, the researcher collected data through an adapted version of Schmitt‟s (1997) Vocabulary Learning Strategies Questionnaire (VLSQ) administering it in different types of schools, Anatolian high school, Private high school and Science high school. The researcher analyzed both discovery and consolidation strategies, including their sub-categories descriptively. The researcher also analyzed the collected data inferentially with reference to gender, grade level, school type and age. The analysis of the data yielded significant results.
