What are Measurement, Statistics, and Evaluation?

Measurement: At its most basic level, the field of Measurement is concerned with the assignment of numbers to objects in some systematic, meaningful way. In education and the social sciences, measurement typically refers to a rational assignment of numbers so that they quantitatively describe some unobservable (i.e., latent) construct like ability, personality, attitude, satisfaction, etc. The assignment of these numbers must proceed in a carefully prescribed, reproducible fashion. In most cases, the process is based on a mathematical model that defines how the numbers should behave as the underlying construct changes. Measurement professionals develop and utilize a variety of mathematical tools to determine the reliability, validity and meaning of the numbers assigned during the measurement process. They are employed in both research and applied settings that involve psychological testing, educational testing, or the measurement of attitudes and preferences. These include large scale testing programs like the SAT and ACT.

Statistics: The field of Applied Statistics is primarily concerned with the development of testable research hypotheses, the application of powerful statistical tests to determine the plausibility of a given research hypothesis, and the design of experiments to control extraneous sources of variation. Other facets of this discipline include the design of schemes to collect sample data that are representative of a given population, the description of a population using alternative characteristics of sample data, and the development of alternative models to explain relationships between observable variables. Additionally, the assessment of model fit and the estimation of model parameters also fall under the rubric of Applied Statistics. Professionals in Applied Statistics develop and utilize quantitative techniques to test hypotheses, develop models for observed data, and assess the adequacy of those models. They are employed in a variety of settings where practical decisions must be made on the basis of observed data (e.g., business, industry, government, and education). These include agencies like the American Institutes fo Research, the U.S. Census Bureau, the National Center for Education Statistics, and a large number of private organizations that conduct surveys or polls.

Evaluation: The field of Evaluation is concerned with the application of measurement and statistical principles to objectively evaluate institutional and organizational programs. Programs are generally evaluated with regard to the way in which they are planned and implemented, and the degree to which they accomplish their mission. Examples of such evaluation efforts include the Tennessee model for evaluating school effectiveness, the extensive work on the effects of teacher training upon student success, and the evaluations of the National Head Start Program. Evaluation professionals might work for the Federal Government as contract monitors, for an industry interested in determining their level of success in marketing, sales, or production, for the State Superintendent of Schools examining the results of large expenditures of time and money, and of course, for a University interested in teaching and research in the systematic application of measurement and statistics to the determination of program value.


The Programs

Measurement, Statistics and Evaluation offers programs of study leading to both the Master of Arts (M.A.) and Doctor of Philosophy (Ph.D.) degrees. M.A. students generally take introductory coursework in measurement, applied statistics, and evaluation. Ph.D. students typically complete an analogous program of study, after which they may continue with a multidisciplinary focus or concentrate primarily on a single discipline.

Most of the educational and social science research that takes place today relies on the expertise of those who develop data collection instruments (such as assessments, questionnaires, and interview protocols), plan research and evaluation studies, develop new models and methods, design sampling frameworks, and collect and analyze data. The University of Maryland programs in Measurement, Statistics and Evaluation provide students with advanced skills in these areas. The master's program gives individuals the broad range of skills necessary to serve as research associates in academic, government, and business settings. The doctoral program qualifies individuals to provide leadership in the conduct of research studies, to serve as applied statisticians, measurement, or evaluation specialists in school systems, industry, and government, and to teach quantitative courses at the university level. We are widely recognized as one of the best applied quantitative programs in the country. Our students are exceptional. Our faculty members are respected leaders within their specialties.



We can usually offer research or teaching assistantships to most of our full-time students. Assistantships are full-time appointments (20 hours per week) that carry both a stipend and a tuition waiver. During a research assistantship, students pursue both individual and collaborative research projects with a faculty member advisor. These appointments are renewable. The duties of teaching assistants range from instructional support (e.g., grading) to taking full responsibility for teaching a section of an undergraduate course (with appropriate supervision and support).


Career Opportunities

There is a tremendous demand for individuals with the quantitative skills provided by our program. Recent surveys of degree programs and employment in measurement show that there will continue to be a shortfall in the number of measurement professionals relative to the number of available employment opportunities. Similarly, the National Science Foundation predicts a strong job market for statisticians over the next ten years.

The need for applied quantitative professionals is strikingly evident in educational research. As education in the United States pushes toward greater accountability and better informed decision making, there has been an ever-increasing demand for professionals who can interpret the abundance of collected data. Each of the nation's 16,000 school districts and each of the 50 state education departments collects large quantities of data to assess the impact of schooling in its community. There are many state and federal data-collection programs, ranging from a regular biennial survey of U.S. schools to specialized cross-sectional and longitudinal surveys. Many of these survey and testing programs result from legislative mandates and they all rely heavily on instrumentation, research design, sampling schemes, and data analysis. Almost all educational research today depends on hard data, rigorous quantitative approaches, and individuals with research expertise. This is a field that is expanding; people recognize that quantitative methods are critical to developing educational theory and are needed to provide a sound foundation for educational progress. As summarized by the American Statistical Association, [People with quantitative skills] concerned with educational issues readily find employment in universities, state and federal government agencies, and private research agencies. The many needs of the education sector for statistical expertise promise exciting careers to all whose interests lie in this field.

Quantitative professionals are not only in high demand, but they also have jobs that are both professionally and personally desirable. The problems that these professionals help solve often have substantial impact on the lives of many other individuals. Additionally, many sources often rank the job of "Statistician" as the most attractive profession with regard to working conditions.


Field Work and Postgraduate Opportunities

Our reputation and location provide tremendous opportunities for our students to conduct special projects and be involved with real-world, often ground-breaking, applications in government, research firms, associations, and private industry. Current and recent students have conducted special projects with or have been employed by American Institutes for Research, The Substance Abuse and Mental Health Services Administration, The Census Bureau, Westat, State Departments of Education, Local Education Agencies, National Education Association, U.S. Department of Education, Educational Testing Service, Maryland Assessment Research Center, Center for Applied Linguistics, and the Center for Biologics Evaluation and Research of the Food and Drug Administration. They also have taken professorial positions at such institutions as Arizona State University, University of Nebraska, University of Georgia, University of Texas - Austin, The George Washington University, University of Houston, Southern Illinois University, University of Hawaii, and University of Maryland Baltimore County.


Student Body

We are committed to maintaining high standards for admission to both our master's and doctoral programs, and we have been able to attract top students from across the United States and the world. Our students come from undergraduate institutions, government, professional associations, consulting firms, research units of companies, and the public schools. Our doctoral students are among the best on any campus. The real-world experiences, skills, and aptitude of our students help make our program intellectually rigorous while providing exceptional peer-to-peer support. Approximately one-half of our students attend full-time, and there is a very active departmental student organization.


Frequently Asked Questions

How many students are in the program?  We currently have approximately 45 students enrolled in our M.A. and Ph.D. programs.

Do I need to have experience in education to be accepted?  No. Our students come from a variety of disciplines both within and outside of education. The dominant characteristic of successful candidates is that they are very interested in the application of quantitative techniques to solve practical problems. Many of these problems arise in educational settings, but others emerge in the social sciences, government, business, and industry.

I have an undergraduate degree (B.A./B.S.) - may I enter directly into the Ph.D. program?  This is a possibility, but very rare. Typically, Ph.D. applicants first complete a relevant master's program. If one completes the EDMS master's program first, then one may apply for the Ph.D. program subsequently. Note that all courses taken as part of an EDMS master's degree apply toward the Ph.D., and the doctoral preliminary examination is waived for those who successfully complete the EDMS master's degree.

Do I need to have a background in mathematical statistics to enter your program? No, but strong quantitative skills and interests are necessary. Undergraduate courses in calculus and linear algebra provide necessary skills for our program.

Do you have many foreign students in your programs? Yes. Approximately 50% of our students are from countries other than the United States. For example, we have strong contingents of students from China and Korea.

What are the admissions criteria? The EDMS Admissions Committee meets regularly during the academic year. Decisions are based on several sources of information including scores on the Graduate Record Examination (GRE), undergraduate transcripts, letters of recommendation, and a statement of interest.

What are the deadlines for admission? Please see the Graduate School web site for current information about admissions for applicants including those holding foreign visas. Our selection committee meets throughout the academic year. However, note that the Graduate School clearance procedures for foreign students can take several months and we do not see your application until these clearances are complete. All applicants should keep track of their applications by visiting the Graduate School web site rather than by e-mailing EDMS.

How much is tuition? Please see the Bursar's Office web site for current information about student tuition. Note that students with full-time teaching or research assistantships, or fellowships, within the Department receive a tuition waiver in the amount of 10 credit hours per semester.

What types of financial aid are available? In addition to Department teaching and research assistantships, the University also offers financial assistance in the form of graduate fellowships, tuition scholarships, support grants, and variety of need-based financial aid programs. However, since financial aid is limited, those applicants who need financial aid should apply as early as possible.

When are classes held? Most classes are held once per week during the evening hours (e.g., 4:15-7:00 PM) so that part-time students with employment/family commitments can attend along with full-time students.

How long does it take a student to finish the program? The degree programs are structured so that a full-time student could finish requirements for the M.A. degree in approximately 2 years whereas approximately 4 years would be required to finish the Ph.D. requirements.

How well does our program accommodate part-time students? Most courses in the department are scheduled during late afternoon or evening hours to enable part-time students to attend classes. Faculty are generally available for consultation during evening hours as well. This provides part-time students with opportunities for both traditional instruction and individual study/research mentored by department faculty. However, some required courses for Ph.D. students require attendance during daytime hours.

The College of Education has long provided instruction in quantitative research methods. Prior to 1964, there was one full-time professor in the area serving a College faculty of approximately 50 members. Although there were recognized areas of specialization, there was, at that time, no departmental structure within the College. Rather, the College operated as a single administrative unit headed by a Dean. During the next ten years there was rapid growth in the size of College, reaching about 200 faculty by the mid-1970s. In this period, several new departments were formed including EDMS around 1972 (we’re a little fuzzy on the exact year). Throughout its history as a recognized area within the College, as a department, and now as a program within the HDQM Department, EDMS has engaged in the dual roles of professional training and service to the College.

In its first role, EDMS has provided training at the master's and doctoral levels for students planning to pursue careers in quantitative areas related to applied statistics, measurement, and evaluation. An important impetus for the development of the major program was a relatively large fellowship program funded in 1966 by Title IV of the Elementary and Secondary Education Act (ESEA). This grant provided support for 12 doctoral students per year with about half of the positions going to EDMS majors and the remainder to minors with majors in other departments within the College. Graduates from the original ESEA fellowship program pursued a variety of important career paths including professorships in higher education, research positions with Maryland boards of education and research posts in the federal government. In fact, one very early graduate went on to become superintendent of the Baltimore City school system. The major program in EDMS had, and still has, a total of about 40-50 full- and part-time students. The number of fulltime faculty in EDMS has fluctuated from six to eight with a budgeted complement of seven at present.

In its second role, EDMS has provided service courses in applied statistics, measurement, and evaluation for graduate students majoring in other departments and programs in the College. In addition, faculty members have always been in high demand as members of doctoral research committees and as consultants to various externally funded projects within the College. This latter activity dates to the very earliest days of EDMS when one current faculty member was partially funded by a grant in the area of pupil personnel services and counselor education. The College has always required some course work provided by EDMS, with courses now in high demand across the campus. The professional training and service roles of EDMS serve complementary purposes. Virtually all full-time graduate students in EDMS are on some form of financial support and many of these students play key roles in service courses. In particular, several EDMS students each semester are employed as teaching assistants (tutors) for students from other units who are enrolled in courses such as EDMS 451, EDMS 645, EDMS 646, and EDMS 651. Also, advanced graduate students serve as primary instructors for the undergraduate EDMS 451 course. In effect, a strong cadre of EDMS graduate students is central to the service teaching role of the department.

Historically, EDMS had not vigorously sought external funding for its own research efforts. While, as noted, faculty members have participated in projects in other units, the procurement of major funding was rarely pursued. However, within the last 10-15 years EDMS has, with great success, focused major effort in the procurement of external funding through both grants and contracts dedicated to efforts specifically in measurement, statistics, and evaluation.
