description: The Measures of Effective Teaching Project (MET)
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 Open-Ended Reading Assessment in grades 4 through 8, Balanced Assessment in Mathematics (BAM) in grades 4 through 8, and the ACT QualityCore series for Algebra I, English 9, and Biology.
Panoramic digital video of classroom sessions were taken of participating teachers and students, teachers submitted commentary on their lessons (e.g., specifying the learning objective) and then trained raters scored the lesson based on classroom observation protocols using the following five observation protocols:

Classroom Assessment Scoring System (CLASS), developed by Robert Pianta, University of Virginia; 
Framework for Teaching, developed by Charlotte Danielson; 
Mathematical Quality of Instruction (MQI), developed by Heather Hill, Harvard University, and Deborah Loewenberg Ball, University of Michigan; 
Protocol for Language Arts Teaching Observations (PLATO), developed by Pam Grossman, Stanford University; 
Quality Science Teaching (QST) Instrument, developed by Raymond Pecheone, Stanford University; 
A subset of the videos also are being scored using an observational protocol developed by the National Board for Professional Teaching Standards (NBPTS) and using the UTeach Observational Protocol (UTOP), developed by the UTeach Preparation Program.
Close to 3,000 teacher volunteers from across the following six, 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 report describes: (1) the educational research and policy context for the study; (2) research questions addressed by MET researchers; (3) the core study design and sub-studies; (4) the realized study sample; (5) additional information on study instruments and derived measures; and (6) the data files available for secondary analysis.; 
Observation Measures Report - This report includes a description of the scoring design used for each phase and each year of the video observation measures and final reports of the scoring carried out for each measure.; 
Randomization File - Year two of the MET study included a process for randomizing the classroom to which teachers were assigned. Information found in the randomization file includes district, school, section and student IDs, teacher IDs for the teacher a student was randomly assigned to, the actual teacher the student was recorded as having in May of that year, and the actual teacher the student was recorded as having in October of that year. Also included in the file are variables that indicate the grade of the student, their randomization block and exchange group and section each student was assigned to.; 
Video Information File - This file contains descriptive information about the videos captured for the MET project. Variables found in the file include the ID of the video, as well as IDs for the district, school, teacher and section related to each video, the subject, grade, and year of the video and whether the file is available for users to view.; 
Subject ID Crosswalk - This file contains only ID variables and is included to describe the associations between districts, schools, teachers, sections and students.; 
Teacher Demographics File - This file contains descriptive information about the teachers in the MET project. Variables found in the file include the ID of the teacher, as well as IDs for the district, gender, race, years experience, and level of education.; 
Student Global ID Crosswalk File - Students were given new and unique IDs in each year of data collection. This file matches those Student IDs across the 2008-09, 2009-10, 2010-11, 2011-12, 2012-13, and 2013-14 academic years.; 
Teacher Global ID Crosswalk File - Teachers were given new and unique IDs in each year of data collection. This file matchers those Teachers IDs across the 2008-09, 2009-10, 2010-11, 2011-12, 2012-13, and 2013-14 academic years.;
description: The MET Study addressed several related research questions: How reliable and valid are the specific measures of teaching effectiveness under study? Do the various measures identify distinctive dimensions of teaching effectiveness, and if so, what dimensions are identified? What measures of effective teaching are empirically related to student learning gains? What does effective teaching look like, and how does it compare to less effective teaching? For example, what is the distribution of teacher scores on measures of effective teaching, and how much difference is there in teacher knowledge scores, teaching practice scores, and student outcome scores among teachers at different points in the distribution of measures of effective teaching? Can multiple sources of data on teachers and their teaching be combined to develop a set of fair, valid, and reliable indicators of teaching quality for use in teacher evaluation systems intended to rank teachers for personnel decision making and to promote teachers' professional learning and development?
description: Teachers at targeted grade levels (4th-9th grade) and in targeted subject areas (English Language Arts, Math and Biology) were recruited from schools in six school districts. Video was captured of these teachers' classroom sessions and these videos were scored using multiple measures to rate teaching method and classroom environment. Multiple assessment instruments and standardized test scores were used to gather student achievement data. Multiple surveys were administered to gather student, teacher and principal opinion on topics such as classroom instruction as well as classroom, school and working environment. Year Two of the study included a teacher randomization.
description: 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..

description: The MET Study began with a process of "opportunity" sampling that took place during July - November 2009 and resulted in six, large school districts volunteering to participate in the study. The process of opportunistic sampling then continued as elementary, middle, and high schools within each district were recruited into the study. Once schools were recruited, opportunity sampling continued as teachers (at targeted grade levels and subject areas) within these schools volunteered for the study. The sampling process resulted in 2,741 teachers from 317 schools in six large school districts being recruited into the first year of the study. Attrition in the teacher sample in Year Two of the study resulted from schools that dropped out of the study (11 schools; 60 teachers). Additionally, individual teachers dropped out when they left their school or district, began teaching a different subject or grade, lost interest in the study, or became ill. Overall, the Year Two sample of teachers included 2,086 teachers in 310 schools. Of the 582 4th and 5th grade teachers in Year Two, the majority continued to be subject-matter generalists who taught English Language Arts (ELA) and Mathematics to a single class of students, although the sample also included a small number of subject matter specialists (who taught ELA or Mathematics to more than one class section of students) and teachers who volunteered only to have their teaching of a single subject be studied. Of the 841 middle-school grade teachers in Year Two, about half continued to be teachers of ELA in grades 6-8, and the other half teachers of Mathematics at these grades. Of the 479 9th grade teachers in Year Two, about a third were teachers of 9th grade English, another third were teachers of 9th grade Algebra I, and another third were teachers of 9th grade Biology.
