State Test Score Trends Through 2006–07

General Information about State Profiles and State Testing Data

The state profiles and testing data posted on this Web site include information that the Center on Education Policy (CEP) and the Human Resources Research Organization (HumRRO) obtained from states by the deadline for CEP's 2008 study of test score trends. The process of collecting and verifying these data began in July 2007 and lasted through April 2008. We are extremely grateful to the state departments of education in the 50 participating states for their cooperation in making these data available and their involvement in verifying the data.

National findings from this study are described in the report, Has Student Achievement Increased Since 2002? State Test Score Trends Through 2006-07, published in June 2008 and available on this Web site.

To assist others in the education and research communities who want to do further research and analysis, we are making available to the public the data we collected from states. These data are extensive and could inform a variety of research questions. The data are available in two forms:

  1. Edited state profiles developed by CEP and HumRRO that give a picture of specific achievement trends in each state and that were used to determine trends for the aforementioned national report
  2. Files with testing data gathered from and verified by states, including test results for additional grades and subgroups not discussed in the national report

All 50 states are represented by some data, but for various reasons several states could not provide all of the requested information. Users of these data should cite the Center on Education Policy as the source of data.

STATE PROFILES

The state profiles posted on this Web site include the following information for each of the 50 states:

  • A summary of key findings about overall achievement and achievement gaps
  • Two tables, one for reading and one for math, summarizing the overall achievement trends (up, down, or no change) and gap trends (narrowed, widened, or no change) at each grade level analyzed in the state
  • Brief descriptions of data limitations in that state and key characteristics of the state's testing system
  • Figures and tables with overall percentages proficient for all years with comparable data and for all grades tested under NCLB
  • Figures and tables with overall cumulative effect sizes for all years with comparable data and for all grades analyzed for this study
  • Tables with test results and achievement gap calculations for the state's main subgroups, shown first in terms of percentages proficient and next in terms of effect sizes
  • A table with the number of test-takers in each subgroup for the starting year and ending year of the trends shown for that state
  • Definitions of key terms used in the profile and caveats about the data

More information on the rules used to analyze and determine trends from the data in the profiles can be found in chapter 2 and appendix 2 of the full report, Has Student Achievement Increased Since 2002?

STATE TESTING DATA FILES

In addition to the state profiles, this Web site contains two data files for each state: XX Proficiency 2007_CEP.xls and XX Scale Scores 2007_CEP.xls (XX stands for the two-character abbreviation for the state name).

Each Excel file contains worksheets for school years 1998-99 through 2006-07. All or part of some worksheets may be blank for a variety of reasons: a) data were not available, do not exist, or could not be obtained from the state or any public source; b) some grades were not tested in the years prior to and soon after 2002 when NCLB was enacted; c) data were not collected at all because they were from a previous test that would not be used in reporting; or d) there was a break in trend between years. In some cases, data from different trend lines are included in the same file if there was a break in trend between years. The proficiency file details the percentage of students in each grade who scored at each state-defined achievement level, for all tested students in the state and for each racial, ethnic, or demographic subgroup (i.e., male, female, white, African American, Latino, Asian, Native American, students eligible for free/reduced lunch, students with disabilities, English language learners, Title I students, and migrant students. (Individual states may use different labels for these subgroups.) For the demographic subgroups, data from comparison groups were also disaggregated (including students who are not eligible for free/reduced lunch, are not low-income, do not have disabilities, or are not English language learners). The top several rows summarize the percentage of students scoring at or above the proficiency cut score. The scale scores file is structured similarly, but contains mean scale scores, standard deviations, and numbers of examinees for each group of students at each grade for each year.

The contents of these Excel files were verified by each state. Only a subset of the data was used in the state profiles for this project; those data cells are highlighted in bold.
