State Data Systems: Virginia
Identifying Effective Teachers Policy
Analysis of Virginia's policies
Virginia does not have a data system that can be used to provide evidence of teacher effectiveness.
However, Virginia 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 Virginia assigns teacher identification numbers, it cannot match individual teacher records with individual student records.
Recommendations for Virginia
Develop capacity of state data system.
Virginia 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."
Virginia has not yet established a definition of teacher of record, which is essential in order to use the student-data link for teacher evaluation and related purposes. To ensure that data provided through the state data system are actionable and reliable, Virginia should articulate a definition of teacher of record and require its consistent use throughout the state.
State response to our analysis

Research rationale
The Data Quality Campaign tracks the development of states' longitudinal data systems by reporting annually on states' inclusion of 10 elements in their data systems. Among these 10 elements are the three key elements (Elements 1, 3 and 5) that NCTQ has identified as being fundamental to the development of value-added assessment.
