Correctional treatment specialist requirements are easy to mix up with the general GS-0101 Social Science series. OPM’s general page prints no semester hour count. The 24 semester hours belong to a separate OPM page for the Correctional Treatment Specialist, which OPM labels “Department of Justice.” That page ties the 24 hours to a degree or to an equivalent combination, not to coursework alone.
PrereqCourses wrote this guide from OPM’s published standard, read October 25, 2026. It shows OPM’s exact wording, the subjects OPM says may be used, what the standard leaves to you, and which online courses match those subjects. For the same rules across nine federal series, see OPM semester hour requirements by series.
This page explains published OPM standards. OPM and the hiring agency’s HR office decide whether coursework qualifies. Upper Iowa University issues the credit. PrereqCourses does not issue credit, and nothing here promises acceptance, a job offer, or credit transfer.

Correctional treatment specialist requirements: what OPM prints
OPM’s Correctional Treatment Specialist 0101 page (retrieved October 25, 2026) carries the label “Department of Justice.” It gives two routes. Both use the same 24 hours.
Route 1: a degree. OPM prints: “Degree that included at least 24 semester hours of course work in the behavioral or social sciences.”
Route 2: a combination of education and experience. OPM prints: “Combination of education and experience that included at least 24 semester hours of course work in the behavioral or social sciences, and that provided applicants with knowledge of the behavioral or social sciences equivalent to a 4-year degree as shown in A above.”
In plain words, there are two routes. The first is a degree that included 24 hours in those sciences. The second is a mix of education and experience where the coursework includes 24 hours and the knowledge adds up to a 4-year degree’s worth. Neither route is 24 hours alone.
The scale behind “equivalent to a 4-year degree” appears on OPM’s General Schedule qualification policies page: “Four years of progressive study or 120 semester hours meets the degree requirements.” OPM does not say how HR should turn that into a score for your transcript. HR decides.
How this differs from the general series. OPM’s Social Science Series 0101 page asks for knowledge “of one or more of the behavioral or social sciences equivalent to a major in the field.” It prints no hour count, so the count is not listed there. If an announcement for a social science job says 24 hours, check which standard it quotes.
The group standard. OPM’s page says to use the Group Coverage Qualification Standard for Professional and Scientific Positions for this series “in conjunction with the Individual Occupational Requirements.” So the 24-hour line is one piece of a larger standard, and HR reads the pieces together.
Check the announcement. The page is labeled “Department of Justice.” It does not say that every agency uses it, and it does not name positions or employers beyond that label. Read the education section of the posting you are applying to and see whether it quotes the correctional treatment specialist requirements or a different standard.
Which subjects OPM says may count
Under OPM’s “Evaluation of Education” heading, the correctional treatment specialist requirements name the subjects directly: “Courses such as sociology, correctional administration, criminal justice, government/political science, psychology, social work, counseling, and other related social or behavioral science courses may be used to satisfy the 24-semester-hour requirement.”
Two details matter:
- “May be used.” The list is a set of examples. HR decides whether each course counts for an applicant.
- Graduate education. OPM says graduate education “must have been in corrections or a related field such as criminal justice, sociology, psychology, counseling, social work, or other course work related to the position.”
OPM also does not say how many of the 24 hours may come from any one subject. That is not listed. It does not say how HR should treat a course that sits between two subjects, such as a criminology course that is part sociology and part criminal justice. Those calls belong to HR.
A practical way to check your own record against the correctional treatment specialist requirements is to sort each course on your transcript under one of OPM’s named subjects, then total the semester hours in each pile. If the piles add up to 24 or more, the correctional treatment specialist requirements for coursework are at least in view. If a course does not fit any named subject, OPM’s phrase “other related social or behavioral science courses” is the only opening, and HR decides whether it applies.
Experience and other conditions
OPM’s experience text says experience must have been gained in one of three kinds of work:
- “casework in a correctional institution or in another criminal justice setting”
- “counseling in any setting, provided it required diagnostic or treatment planning skills to achieve specific social or occupational goals”
- “work treating persons in need of social rehabilitation”
Whether your work fits one of these is for you to document and for HR to judge. PrereqCourses does not offer experience. OPM’s wording is specific about settings: a correctional institution or another criminal justice setting for casework, any setting for counseling that required diagnostic or treatment planning skills, and work treating people who need social rehabilitation.
OPM’s page also lists medical requirements for this series. They are outside the scope of this guide, so read that section of the OPM page directly.
Which online courses fit the subjects OPM names
Upper Iowa University (UIU) courses on PrereqCourses are self-paced, begin on the 1st of each month, and give you 6 months to finish. Every course below is 3 semester hours and costs $675, read from each live product page on October 25, 2026. Textbooks are purchased separately.
Upper Iowa University (UIU) is accredited by the Higher Learning Commission (hlcommission.org), an institutional accreditor recognized by the U.S. Department of Education. OPM asks that education come from an institution accredited by an accrediting body recognized by the U.S. Department of Education, and OPM and the hiring agency’s HR office decide whether coursework qualifies, so confirm with the announcement.
OPM’s list names these subjects, so the courses below may fit the correctional treatment specialist requirements. “May fit” means the subject matches OPM’s wording. It does not mean HR will count the course.
Our course guides cover the larger groups in more depth for readers working through the correctional treatment specialist requirements. See general psychology courses, abnormal psychology courses online, the online intro to sociology course and online psychology courses for credit. If correctional work interests you from a clinical angle, our guide to a forensic psychologist career mentions correctional settings.
Example arithmetic, not a recommendation. CJ 224, CJ 333, CJ 380, SOC 110, PSY 190, PSY 360, PSY 302 and PS 100 are 8 courses and 24 semester hours. At the current price that is 8 x $675, or $5,400. The example shows how the total works. It does not mean HR would count each course. OPM also states that “Additional credit cannot be given for duplicate course work,” so avoid pairing courses with overlapping content.
What PrereqCourses does not offer
Correctional treatment specialist requirements ask for more than a list of courses. Here is what PrereqCourses does not supply:
- A degree. The 24 hours sit inside a degree or an equivalent combination. PrereqCourses does not offer a degree, so 24 hours of coursework alone does not meet the standard.
- Social work or counseling courses. OPM names both subjects. The catalog has no social work or counseling course, and no course titled “correctional administration.”
- Experience. OPM’s experience text is for you to document.
- Any assurance that HR counts a listed course. HR decides, and an announcement may read differently from OPM’s page.
If your degree is in an unrelated field, the combination route needs knowledge equivalent to a 4-year degree plus the 24 hours. Our guide to prerequisite courses for career changers explains how self-paced credit fits around work, and the guide to accredited online prerequisite courses explains what accreditation means for credit.
Accreditation, online credit and transcripts
OPM’s policies page defines accredited education as study “accredited by one of the accrediting agencies or associations recognized by the Secretary, U.S. Department of Education.” On distance learning it says:
“Correspondence or distance learning course work is also acceptable if the applicable school within the institution or applicable curriculum is accredited by an accrediting body that is recognized by the Secretary of the U.S. Department of Education. The distance learning courses should indicate the credit hours for each course and be indicated on the degree transcript together with traditional course work and credits.”
The second sentence is about how credit appears on a transcript. It does not say a separate transcript is refused, and it does not say one is accepted. HR decides.
Documentation is your job. OPM says: “It is the applicant’s responsibility to provide documentation or proof that he or she has met the applicable educational provisions.” It adds that “An official transcript; statement from the institution’s registrar, dean, or other appropriate official; or equivalent documentation is acceptable.”
Credit for these courses is issued by Upper Iowa University (HLC). Your official transcript comes from UIU and does not mention PrereqCourses. UIU charges $10 per copy through its transcript ordering center, as described in our FAQ.
Quarter hours. If your earlier school used quarters, OPM prints that “30 semester hours or 45 quarter hours is comparable to 1 year of undergraduate education.” A quarter hour is therefore worth about two thirds of a semester hour, so 24 semester hours is about 36 quarter hours. That ratio is worked out from OPM’s figures and is not printed by OPM.
Steps before you apply
- Read the education section of the announcement, not a summary of it.
- Check that it uses the OPM Correctional Treatment Specialist standard.
- Compare your transcript with the subject list, course by course.
- Ask the HR contact on the announcement how they count your coursework.
- Fill gaps last, and only the gaps that are left.
PrereqCourses offers a free advisory session about prerequisite planning. It does not speak for OPM or for any agency’s HR office.
Frequently asked questions
How many semester hours do correctional treatment specialist requirements call for?
For the correctional treatment specialist requirements, OPM’s page prints 24 semester hours of course work in the behavioral or social sciences. Those hours go inside a degree, or inside a combination of education and experience that provided “knowledge of the behavioral or social sciences equivalent to a 4-year degree.” OPM and the hiring agency’s HR office decide whether coursework qualifies.
Does criminal justice count toward correctional treatment specialist requirements?
OPM names criminal justice in its list of courses that “may be used to satisfy the 24-semester-hour requirement.” HR decides whether a given course counts, so check your announcement.
Can I meet correctional treatment specialist requirements without a degree?
Only through the combination route. It requires 24 semester hours in the behavioral or social sciences plus knowledge “equivalent to a 4-year degree,” with experience or additional education. HR decides how a combination is read.
Do online courses count toward correctional treatment specialist requirements?
OPM says distance learning course work “is also acceptable if the applicable school within the institution or applicable curriculum is accredited by an accrediting body that is recognized by the Secretary of the U.S. Department of Education.” Courses are taught and credited by Upper Iowa University, accredited by the Higher Learning Commission. OPM and the hiring agency’s HR office decide whether coursework qualifies.
Where this leaves you
Correctional treatment specialist requirements come down to 24 semester hours in the behavioral or social sciences, inside a degree or a combination equivalent to one. PrereqCourses has courses in most of the subjects OPM names, including sociology, criminal justice, psychology and political science. It does not have a degree, experience, or social work and counseling courses.
For the same rules across nine federal series, see OPM semester hour requirements by series. This page explains published OPM standards.
