MET 3b - Item-Level Supplemental Test Files, 2009-2011

The MET project is based on two premises: First, a teacher's evaluation should depend to a significant extent on his/her students' achievement gains; second, any additional components of the evaluation (e.g., classroom observations) should be valid predictors of student achievement gain.

Student achievement was measured in two ways -- through existing state assessments, designed to assess student progress on the state curriculum for accountability purposes, and supplemental assessments, designed to assess higher-order conceptual understanding. The supplemental assessments used were:

  • Stanford 9 (SAT 9) Open-Ended Reading Assessment in grades 4 through 8
  • Balanced Assessment in Mathematics (BAM) in grades 4 through 8
  • ACT QualityCore series for Algebra I, English 9, and Biology (ACT)

Close to 3,000 teacher volunteers from across the following 6, predominantly urban, school districts participated in the MET project: Charlotte-Mecklenburg Schools, Dallas Independent School District, Denver Public Schools, Hillsborough County Public Schools, Memphis City Schools, and the New York City Department of Education. Participants teach math and English language arts (ELA) in grades 4-8, Algebra I, grade 9 English, and high school biology.

The Item-Level Supplemental Test Files release consists of data files for the three supplemental assessments (SAT 9, BAM, and ACT).

2013-09-01 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Created variable labels and/or value labels.
  • Checked for undocumented or out-of-range codes.
