Everyday, special education teachers must decide what to teach, how to respond to students, when to change instructional programs, and what changes to make -- and at the same time demonstrate student progress. This book helps teachers and direct care providers increase student successes by giving them guidelines to make more informed decisions about instruction. All teachers want their students to learn as much as they can as fast as they can. This book will help teachers make instructional plans more effective and efficient by showing them how to gather and use student performance data.
