Testimony by Dr. Lori Mei concerning the Y2005 New York City Test Scores

Testimony to the New York City Council Committee on Education
By Dr. Lori Mei
Hearing on Test Results, June 27, 2005


Good morning Councilwoman Moskowitz and members of the Education Committee. I am Dr. Lori Mei, Senior Instructional Manager of the Department of Education's Division of Assessment and Accountability and I am here to discuss our testing program and the recently released city test results. With me is Jennifer Bell-Ellwanger, Deputy Senior Instructional Manager for Assessment and Accountability. Also here today are senior staff from the testing companies that develop and score our City tests at grades 3, 5, 6 & 7. These companies, CTB/McGraw-Hill and Harcourt Assessment, Inc., are two of the largest and most respected testing companies in the country. They develop and independently score NYC's mathematics and English Language Arts tests. Later this morning, Dr. Daniel Lewis from CTB/McGraw-Hill and Dr. John Olson from Harcourt Assessment will discuss the development and psychometrics of the City's mathematics and ELA assessments respectively.

As in previous years, the 2005 City ELA and Mathematics tests were developed to assess students' mastery of State and City learning standards. As the testing companies will explain in greater detail, these tests are valid and reliable measures of our students' attainment of these standards. Our City tests are developed and scored according to the highest industry standards by CTB/McGraw-Hill and Harcourt Assessment. We hire the testing companies specifically for their expertise in constructing standardized tests, ensuring that the tests are similar from year-to-year and scoring the tests. As a result of the processes that the testing companies have in place, we can be sure that the tests are comparable from one year to the next and that improvement can be attributed to students' increased knowledge and skills and is not the result of differences in how the tests are developed. I am confident that they have done their work with care, with integrity and according to the Standards for Educational and Psychological Testing.

I have been with the Department for over 20 years, and I have served many Chancellors. I was appointed head of the Division of Assessment and Accountability by Chancellor Levy in 2001 and served as Deputy for a number of years before becoming Executive Director. I hold a B.A. from Smith College and a Ph.D. in Social Psychology from Teachers College, Columbia University where I focused on educational research and multivariate statistics.

First as deputy and, for the last several years as head of the office, I have overseen the testing process, utilizing the same high standards and careful review year after year. This year, as in previous years, I conducted a thorough review of the content and format of the City tests developed for us by our test publishers, and I examined the technical material supplied by the testing companies' psychometricians.

As the testing companies will explain to you in detail and as I can confirm, the 2005 tests are valid and reliable. The increased scores mean that our children simply performed better on these tests this year.

Further, I would like to dispel a number of inaccuracies and misconceptions that I have heard raised about students' performance on the City tests and on the State grade 4 ELA assessment this year.

At this point, let me describe in more detail the review processes that the Department has in place regarding our city testing program.

1. As previously indicated, both the City ELA and Mathematics assessments are designed to measure students' attainment of New York State Learning Standards and New York City Performance Standards. As the testing companies will explain in greater detail, each item on the test for each subject and grade is designed to measure a specific skill. The tests are constructed by the testing companies from the respective company's pool of items aligned to the standards. The test publishers provide the content in terms of both the passages and items for the tests.

2. Research staff from Harcourt and CTB/McGraw-Hill provide NYC Assessment staff with a variety of statistical data for each item under consideration. DOE Assessment staff review the passages and items selected by the test publishers and item statistics and approve the final form of the tests.

3. As is the process for all standardized test development, the NYC ELA and Mathematics test items are piloted by the testing companies on stratified random national or New York samples of students. We have made sure that our City tests have been piloted on samples of students that are representative of our New York City population. The testing companies construct the tests so that they represent a range of items from easy to difficult.

4. Once the tests are administered, the test answer documents are scanned at DOE's Scan Center and electronic files of each student's answer to each test item are sent to the respective testing company for scoring.

5. The Research staff at Harcourt and CTB/McGraw-Hill apply their equating and calibration programs and score the tests.

Both companies conduct extensive quality control checks on the input (e.g., raw score) files and output (e.g., scaled score) files and both companies have certified that the raw score-to-scaled score conversion tables that they provided to NYC are valid and reliable.

To reiterate, our City tests are developed and scored by independent, respected test publishers according to the highest industry standards. We hire the testing companies specifically for their expertise in constructing standardized tests, equating different test forms and scoring the tests. Through their equating processes, the overall difficulty of test forms is statistically adjusted so that we can be sure that the tests are comparable from one year to the next and improvement can be attributed to students' increased knowledge and skills and are not the result of differences in how the tests are constructed.

I hope that this clarifies matters for you, I will be happy to take any additional questions that you may have.
