Overview FAQs

As an educational diagnostician, you evaluate students who may have disabilities or other special learning needs, administer and interpret diagnostic assessments, and help schools land on the right support plan for each student. TAMIU's Educational Diagnostics Professional Certificate is a 24-credit-hour program you can complete in about 8 months, built around diagnostic assessment instruments, intelligence and ability testing, and academic achievement assessment, and it's designed to align directly with the TExES Educational Diagnostician (253) certification exam. Your coursework also covers evidence-based practice for students with disabilities, special education law and ethical responsibility, psychometrics, a supervised practicum, and embedded field experience in youth mental health, substance abuse, youth suicide awareness, and dyslexia. You can see the full course sequence on the Courses tab. With this credential, you can move into roles like Special Education Coordinator, Director of Special Education, Educational Consultant, or university faculty and program evaluator positions, and TAMIU reports a 95% pass rate on the TExES Educational Diagnostician exam among its graduates. If you want to talk through whether this path fits your teaching background, call TAMIU's enrollment team at (844) 872-8712.
Both roles evaluate students for special education needs, but they work differently. An educational diagnostician's certification focuses specifically on diagnostic assessment and eligibility determination within the school system, while a school psychologist's license covers a broader scope that includes mental health counseling and behavioral intervention. TAMIU's Educational Diagnostics Professional Certificate is built for licensed Texas teachers who want to add the diagnostician certification to their credentials rather than pursue a full psychology degree: you'll need a master's degree already in hand, a valid Texas teaching certificate, and at least three years of teaching experience, and the certificate itself is 24 credit hours over 8 months, including a 160 clock-hour practicum. If your goal is administering and interpreting diagnostic evaluations in a K-12 special education setting and you already have a teaching background, the educational diagnostician path through TAMIU is typically the more direct route. Call an enrollment counselor at (844) 872-8712 to compare this certificate against other credential paths based on your background.
Yes. TAMIU delivers the Educational Diagnostics Professional Certificate 100% online. Courses run in 7-week terms with six start dates a year, and you can complete the full certificate, 24 credit hours across eight core courses, in about 8 months. Check the Calendar tab for upcoming start dates. The one piece that takes you outside coursework is the required Practicum Educational Diagnostics course, which places you in a supervised setting to complete diagnostic assessment work, though the coursework itself stays online. This online format and multiple annual start dates are built around a working teacher's schedule, so you don't have to pause your classroom job or relocate to complete the certificate. Call (844) 872-8712 to confirm the next available start date for your schedule.
Yes. The certificate is built to align with the TExES Educational Diagnostician (253) exam, the state exam Texas requires for educational diagnostician certification. Your curriculum covers diagnostic assessment instruments, intelligence and ability testing administration and interpretation, academic achievement assessment, psychometrics, and a 160 clock-hour supervised practicum, mapped directly to the skills the TExES 253 exam tests. TAMIU reports a 95% pass rate on the TExES Educational Diagnostician exam among its graduates, and program faculty bring direct K-12 special education practitioner experience, with some having served on state boards of education. TAMIU states on its program page that its College of Education is accredited by the Texas State Board for Educator Certification. Because the coursework is built around the state exam content and the practicum gives you supervised, hands-on assessment experience before you sit for the exam, the program is designed to move you from certified teacher to certified educational diagnostician without unrelated coursework. Call (844) 872-8712 to talk through the certification timeline with an enrollment specialist.
If you're already a licensed Texas teacher with at least three years of classroom experience and a master's degree, this certificate is built specifically for you. It targets educators who want to move from classroom teaching into a diagnostic, evaluative, or special education leadership role, using a focused 24-credit-hour, 8-month path rather than a full second degree. If you don't yet hold a master's degree or a Texas teaching certificate, or don't yet have three years of teaching experience, you'll want to review the admissions requirements before applying. For teachers who already meet the entry requirements, the certificate offers a direct, exam-aligned route to a new certification and career track, backed by TAMIU's reported 95% TExES Educational Diagnostician exam pass rate. If you're unsure whether your background qualifies, call TAMIU's enrollment team at (844) 872-8712.

Tuition

Pay-as-you-go tuition helps make this online Educational Diagnostics Professional Certificate program affordable

Tuition for the Educational Diagnostics Professional Certificate online program is affordable and can be paid by the course. All fees are included.

Tuition FAQs

Tuition is billed per credit hour and varies by residency status across the certificate's 24 credit hours, with all fees included in the published rate. Rates are subject to change, so see the current tuition and fees breakdown on the program page for exact costs. There's also a $35 application fee. Because the program runs in 7-week terms with six start dates a year, you can budget and pay across a shorter timeline than a traditional academic-year program, with tuition billed by credit hour rather than as a single lump sum. Relative to other specialized certifications, it's a comparatively low-cost path that can support a move into higher-paying special education leadership roles. For a personalized cost breakdown based on your residency status, call (844) 872-8712.
TAMIU's Office of Financial Aid works with certificate students to identify eligibility for federal financial aid, including federal student loans, through the FAFSA process. Because this certificate is a graduate-level credential rather than a full degree, your aid eligibility depends on your enrollment status and program classification, which financial aid staff can confirm directly. Many students in this program are also currently employed as teachers, so district-based tuition assistance or employer reimbursement may be worth exploring alongside federal aid; TAMIU's program page doesn't list a dedicated scholarship program for this certificate. Combining any available district support with federal aid can meaningfully offset the in-state program cost, especially when paid across the program's 7-week terms rather than all at once. Call TAMIU's financial aid office at (844) 872-8712 to review your options before you apply.

Calendar FAQs

Yes. The program is designed for working Texas teachers and is delivered 100% online in 7-week terms. The full certificate totals 24 credit hours across eight courses and is designed to be completed in about 8 months, a pace built around the schedule of full-time educators rather than requiring a career pause. The one piece that requires dedicated time outside regular coursework is the 160 clock-hour practicum, which you'll need to plan around your teaching schedule and district calendar. Because admission requires you to already be a licensed, experienced teacher, TAMIU has structured the certificate specifically so current classroom teachers can add this credential without leaving the workforce. To talk through how the practicum and course schedule would fit around your current teaching job, call (844) 872-8712.
TAMIU offers six start dates a year for the Educational Diagnostics Professional Certificate, so you're not limited to a single once-a-year enrollment window the way you would be with a traditional fall-only academic calendar. Because each 7-week term opens a new entry point, this frequency lets you start as soon as your application and required documents, including your service record and screening survey, are complete, rather than waiting months for the next opportunity. For current start dates and deadlines, see the program calendar. Call (844) 872-8712 to confirm the application deadline for the start date you want.

International Transcript Evaluation:
TAMIU does their own foreign credential evaluations. Graduate School does not require third party evaluations nor are obligated to accept the results, or GPA calculations, if an evaluation is submitted. If an applicant submits an official evaluation, the evaluation does not replace official transcripts or certificates of graduation.

Admissions FAQs

To enroll, you'll need a master's degree in education or teaching, a minimum 2.75 GPA on your last 60 academic hours, and a valid Texas teaching certificate. TAMIU also requires a service record documenting at least three years of teaching experience, a 300-word personal statement describing your career goals and certificate timeline, a completed College of Education application, a Code of Ethics form, FERPA consent, and completion of the College of Education's online screening survey. All required documents upload directly to TAMIU's application portal, and the Educational Diagnostics Screening Instrument Form is due within 30 days of admission, not before you apply. TAMIU's program page doesn't publish a specific transfer-credit policy for this certificate, so if you're bringing in graduate coursework from elsewhere, an admissions counselor will need to review your transcripts directly. Because the requirements center on your existing teaching license and classroom experience rather than new standardized testing, most working Texas teachers who meet the GPA threshold and certification requirement are well positioned to qualify. For a personalized document checklist, call TAMIU admissions at (844) 872-8712.
You apply by submitting a College of Education application along with your transcripts, teaching certificate, and required supporting documents through TAMIU's application portal. Required materials include official transcripts showing your master's degree, proof of a minimum 2.75 GPA on your last 60 hours, a valid Texas teaching certificate, a service record documenting three years of teaching experience, a 300-word personal statement, a Code of Ethics form, and FERPA consent. If your degree wasn't earned in the U.S., you may also need to submit TOEFL or IELTS scores. TAMIU evaluates foreign transcripts internally rather than requiring a third-party credential evaluation service, and documents you've already uploaded to the portal shouldn't also be mailed separately, since that can delay processing. Because the requirements center on documentation you likely already have as a certified, experienced teacher, most applicants can assemble a complete file without new coursework or testing first. Call (844) 872-8712 for a document-by-document walkthrough before you submit your application.

Courses FAQs

The certificate requires a dedicated Practicum Educational Diagnostics course totaling 160 clock hours of supervised field experience. It's one of eight core courses in the 24-credit-hour program and gives you hands-on experience administering and interpreting diagnostic assessments under supervision, building on your coursework in measurement and evaluation, psychometrics, and academic achievement assessment. Practicum placement is one of the most common questions from prospective students in this program, since logistics vary by district and availability, and TAMIU's program page doesn't publish a standardized placement process, so you'll want to confirm specific site arrangements directly with the program. Completing a supervised practicum before you take the TExES Educational Diagnostician exam gives you applied experience that classroom coursework alone can't, and it's a required step toward certification. To ask about practicum placement in your district or region, call TAMIU's enrollment team at (844) 872-8712.
