Mastery-based progression is an innovative and transparent system of tracking student progress and reflecting individualized growth. This grading and reporting system focuses on progress towards mastery of the Texas Essential Knowledge and Skills (TEKS) and will reflect and document all student growth, proficiency and academic objectives as well as academic behaviors which include social and ethical behaviors that contribute to overall student success. A student will demonstrate a level of mastery according to an assigned performance level. Mastery is defined as knowing and understanding the skill or concept and applying it to more complex in-depth learning demonstrated through a performance-based assessment. These assessments can be composed of complex problems and/or student work products related to the skill or concept.
