Grade by grade, the range in achievement widens between the most successful students in each classroom and those least successful. Providing optimal instruction and activities for all students becomes more of a challenge to the teacher of each succeeding grade.

ASCL provides professional development to expand teachers' instructional skills so that they can increase student achievement and address gaps in student exposure to standards-based curriculum. Training strategies are designed using scientifically collected data to help modify instructional techniques and to develop strategies that address different learning modalities. Seminars are developed to provide an in-depth focus on one or more of the areas identified by the assessment data that is collected.
