Teacher and Principal Evaluation Policy
The data and analysis on this page is from 2019. View and download the most recent policy data and analysis on Measures of Student Growth in District of Columbia from the State of the States 2022: Teacher and Principal Evaluation Policies report.
Impact of student growth: The District of Columbia no longer requires that objective evidence of student growth be a "significant" criterion of its teacher evaluations. Only LEAs receiving Race to the Top funding must incorporate student learning as a component of every teacher's evaluation.
State's role in evaluation system: The District of Columbia provides criteria and approves district-designed evaluation systems.
Require objective measures of student growth to be included in teacher evaluation.
The District of Columbia should require that objective measures of student growth be included in a teacher's evaluation rating, and that such measures play a profound role in a teacher's overall evaluation rating.
The District of Columbia noted that although it does not require that objective evidence of student growth be a criterion of its teacher evaluations, it does recommend that objective evidence of student learning be a "significant" criterion of its teacher evaluations, that teachers meet student growth goals, and that to be to be rated overall effective, teachers should be rated at least effective for the student growth portion. The District of Columbia added that the IMPACT system, the teacher and school leader evaluation and feedback policy implemented by District of Columbia Public Schools (DCPS), requires teachers to set student achievement goals specific to their subject areas. Many DCPS teachers also have a value-added measure to assess student learning growth.
The District of Columbia also noted that state policy requires LEAs to report data points based on guidelines mandated under the Every Student Succeeds Act (ESSA) in compliance with the equitable access initiative that ensures low-income students and minorities are not disproportionally served by out-of-field, inexperienced, and ineffective teachers. The law does not set specific requirements for the various components of the teacher evaluation system. The state allows LEA autonomy and flexibility in this area.
7A: Measures of Student Growth
Many factors should be considered in formally evaluating a teacher; however, nothing is more important than effectiveness in the classroom. Value-added models are an important tool for measuring student achievement and school effectiveness.[1] These models have the ability to measure individual students' learning gains, controlling for students' previous knowledge and background characteristics. While some research suggests value-added models are subject to bias and statistical limitations,[2] rich data and strong controls can eliminate error and bias.[3] In the area of teacher quality, examining student growth offers a fairer and potentially more meaningful way to evaluate a teacher's effectiveness than other methods schools use.
Unfortunately, districts have used many evaluation instruments, including some mandated by states, which are structured so that teachers can earn a satisfactory rating without any evidence that they are sufficiently advancing student learning in the classroom.[4] Teacher evaluation instruments should include factors that combine both human judgment and objective measures of student learning.[5]
