Assessment and Program Evaluation

  • The Assessment Department at Tigard-Tualatin School District is responsible for facilitating the administration of standardized assessments and promoting the effective use of assessment data within the district.  Assessments provide educators with measurable data of student performance on both behavioral and academic expectations.  Such information can be used to evaluate student abilities, inform classroom instruction, and improve educational programs.

  • Screening and Progress Monitoring tests are short, targeted assessments which provide teachers with a quick indication of a student's skill level and the possible need for educational interventions.
