Graduate Programs


The primary goal of graduate study in psychology at Oklahoma State University is to produce scholars-researchers with sufficient breadth and depth to permit successful independent and significant research. While major emphasis is given to the preparation for research, organized and concerted effort is also made to give students the necessary background for teaching, practice, or any combination of these fields. The department admits only full-time students planning to work toward the Ph.D. degree. The M.S. degree is awarded as the first step in doctoral training. Throughout training, students develop skills in research, teaching, and other professional activities integral to psychology.

The Department of Psychology is proud of the academic and cultural diversity of its students, faculty, and staff. The department encourages applications from diverse candidates as part of its effort to maintain and advance a rigorous and well-informed academic community.

About the University

Oklahoma State University is located in Stillwater, a city of 47,000 located in north central Oklahoma. The university is coeducational and has an enrollment of approximately 32,000 students on its four campuses. Approximately 23,537 are on the Stillwater campus. The graduate student enrollment totals 4,589. Of these students, 57 percent are from Oklahoma, 17 percent are from other states, and 30 percent are from foreign countries.

The university is committed to equal educational opportunity. Students and faculty are selected without regard to ancestry, sex, age, religion, lifestyle, or handicap condition. Oklahoma State University, in compliance with Title VI and VII of the Civil Rights Act of 1964, Executive Order 11246 as amended, Title IX of the Education amendments of 1972, American with Disabilities Act of 1990, and other federal laws and regulation, does not discriminate on the basis of race, color, national origin, sex, age, religion, disability or status as veteran in any of its policies practices or procedures. This includes but is not limited to admissions, employment, financial aid and educational services.


Any bachelor's or master's degree can be the basis for seeking admission, provided the applicant has completed adequate preparation for graduate study in psychology. Adequate preparation normally involves substantial coursework in Psychology, including the following recommended courses: Introductory Psychology, Experimental Psychology/Research Methods, and Statistics/Quantitative Methods in Psychology. Applicants to the clinical psychology program are also recommended to have taken History of Psychology if their undergraduate degree is not in Psychology. If otherwise admissible, clinical applicants lacking History of Psychology will be required to acquire this course after their admission to the program. Applicants who have done outstanding work in related areas of study but who do not have the recommended undergraduate psychology courses, may also apply for admission. Such students may be asked to make up some undergraduate courses after admission. In most cases, however, satisfactory performance in graduate-level core courses is sufficient to remove any undergraduate deficiencies

Factors generally helpful in gaining admission to the program include career goals consistent with the training objectives of the training programs, a high undergraduate grade point average, high scores on the Graduate Record Examination, strong letters of recommendation, demonstrated ability to communicate effectively, evidence of quantitative and research skills, and evidence of interest and commitment to one or more aspects of psychology represented by department faculty. Additionally, for the clinical psychology program, evidence of interpersonal skills is an essential factor.

Both departmental programs require full-time enrollment and on-campus presence. This is not an online program.


Application and Admission

To apply for either program, complete an application online by clicking here

We do not require that applicants have a bachelor's degree in psychology. We do require, however, that the applicant have specific courses on the transcript. These are Introductory Psychology, Experimental Psychology, Quantitative Methods in Psychology, and History of Psychology. If otherwise admissible, students lacking History of Psychology will be permitted to acquire this course after their admission to the program. Abnormal Psychology is recommended if the student is applying to the Clinical Program. Naturally, grades of "B" or better are highly recommended. Students who are successful in their application typically have GPA's of 3.3 or higher. 

We require three letters of reference. These letters should be from psychology faculty from whom you have taken classes or under whom you have carried out research. If you are applying to the Clinical Program, it is advisable that you include letters from individuals with whom you have worked that can attest to your abilities, industriousness, interpersonal facility, stability, and so forth. Be aware that letters of reference should contain specifics about the referee's knowledge of you. Positive general letters of reference are not especially helpful to us.

We require a two- to four-page Statement of Purpose. This statement should be typed and well-written. This statement should address (a) why you want to become a psychologist, (b) experiences you have had that enhance your psychology application, (c) future plans after you achieve the doctorate, etc. For those applying to the Clinical Program, carefully chronicle any job experience in the helping professions, especially any jobs relating to mental health. Include both paid and volunteer experience in these areas.

We require that you submit a paper representative of your writing abilities, preferably from an experimental psychology course, a convention paper presentation, or a manuscript submitted or accepted for publication. If one of these is not available, any paper from a psychology course will suffice. Please note, however, that the paper will be examined for evidence of both writing skills and research expertise.

One very important requirement for admission is taking the general aptitude tests of the Graduate Record Examination. Average GRE aptitude score for our admitted students is 300 for verbal and quantitative combined. It can pay to do extensive preparatory study for these examinations. The computer based general GRE is given year-round. Please note our deadlines. Scores from November examinations often do not reach the Department until after January 1st. Registration forms can be obtained through testing offices at most universities and colleges. GRE scores will not be accepted if over five years old. GRE scores will not be required for those applying for 2024 fall admission.

Please send your materials as soon as possible. Early submission of materials allows for early review so that if a critical item is missing we can notify you. Please submit your materials to the Psychology Department by December 1st for both clinical and experimental psychology programs. Students from minority groups are actively encouraged to apply.

Financial Support

The Department of Psychology recognizes that students who enter graduate school typically have both the need and the desire to be self-supporting. Since our graduate training programs aim at high-level professional training, we believe that every student should be provided with adequate financial support to complete the program. The Department does not encourage graduate students to enroll in the programs while supporting themselves with a job not associated with their academic pursuits.

The Department's goal is to provide some financial support for all graduate students through teaching assistantships, research assistantships, fellowships, and traineeships. The Department also helps students locate other sources which can support their graduate training. Although it is not always possible to do so, the Department is committed to the concept of student support because of the desirability of students devoting full-time attention to graduate work.

Support Services

Special activities are designed to introduce students to the academic and social resources available in the Department, across campus, and in the community. Throughout the student's graduate career, the department offers support services through the Psychology Diversified Students Program, the American Indians Into Psychology Program, and the Psychology Graduate Student Association. We provide students with information about financial aid and support services within the department.


The Department of Psychology is located in North Murray near the center of the OSU campus. All students are provided with an office. The department owns a wide variety of equipment for research and instructional purposes. Laboratories are equipped with microcomputers for automatic presentation of stimuli, recording psychophysiological data and other response parameters, controlling experiments, and establishing data files. Well-equipped laboratories for comparative and physiological work are available as well.

The department operates the Psychological Services Center, an on-campus facility for clinical work and research. The Center has equipment and facilities to accommodate a number of specialized services and functions, including biofeedback, play therapy, videotaping, direct observation of clinical work using one-way mirrors, and direct supervision through telephones placed in therapy rooms. The department maintains liaison with many off-campus organizations and agencies which provide the student with access to special populations for research as well as clinical activities.
