The state should have a data system that contributes some of the evidence needed to assess teacher effectiveness.
Oregon does not have a data system that can be used to provide evidence of teacher effectiveness.
However, Oregon does have two of three necessary elements that would allow for the development of a student- and teacher-level longitudinal data system. The state has assigned unique student identifiers that connect student data across key databases across years, and it has the capacity to match student test records from year to year in order to measure student academic growth.
Although Oregon assigns teacher identification numbers, it cannot match individual teacher records with individual student records.

Develop capacity of state data system.
Oregon should ensure that its state data system is able to match individual teacher records with individual student records.
Develop a clear definition of "teacher of record."
A definition of teacher of record is necessary in order to use the student-teacher data link for the purpose of providing value-added evidence of teacher effectiveness. According to the state, it has established a definition of teacher of record. However, to ensure that data provided through the state data system are actionable and reliable, Oregon should articulate a more distinct definition of teacher of record and require its consistent use throughout the state.
Oregon recognized the factual accuracy of this analysis. The state added that the technical staff at the Office of Assessment and Information Services (OAIS) is in the process of connecting teacher and student records; however, the specific requirements are vague and unclear. Oregon noted that OAIS would appreciate more clarity with respect to the business rules for connecting student and teacher records as well as a better understanding of the types of questions that need to be answered.
The Teacher-Student Data Link Project, administered by the Center for Educational Leadership Technology (CELT), would be an excellent resource to answer the state's questions.
