1 & Done vs Therapist Development Center for the MFT licensure exam
1 & Done Exam Prep is a fixed-term, judgment-first MFT licensure exam program built around daily text-message practice. Therapist Development Center (TDC) is a coaching-based online program for the MFT and social work licensing exams, known for its “with you until you pass” pledge — pay once and extend free if you need more time. Both are legitimate, independent study tools — this page lays out where each is stronger so you can choose on facts, not ads.
1–3 questions delivered by text message each day — no app to open
Coaching
Live coaches answer study questions as you work through the course
Coaching is embedded in the rationales — every answer choice explains why it wins or loses — rather than via live humans

Why the best answer wins and why each tempting alternative loses (FIRST / NEXT / BEST judgment)

Fixed terms of 1, 3, 6, or 12 months that never auto-renew

Which one fits how you study?
Choose Therapist Development Center if…
You want live human coaches available when you get stuck.
You want the security of keeping your course until you pass, with free extensions.
You learn well from audio lessons and structured study strategies.
You are taking a California MFT or social work exam — TDC's longtime focus.
Choose 1 & Done if…
You keep narrowing questions to two plausible answers and losing points on judgment, not knowledge — our rationales coach the FIRST / NEXT / BEST decision the exam rewards.
You want a daily study habit that arrives by text message instead of requiring you to open an app.
You want to rehearse branching clinical cases where each decision changes what happens next.
You want a fixed term that never auto-renews — and, on pay-in-full Jog or Marathon, reimbursement toward a verified retake fee instead of more access time.

Comparison FAQ
Is 1 & Done affiliated with Therapist Development Center or AMFTRB?
No. 1 & Done Exam Prep is an independent exam-preparation resource and is not affiliated with, endorsed by, or approved by Therapist Development Center, AMFTRB, or any licensing board. Therapist Development Center is a trademark of its respective owner, which is likewise independent of AMFTRB.
How do the guarantees differ?
TDC's pledge is continued access: if you need more time, the course extends free until you pass. 1 & Done keeps the study term fixed and, on pay-in-full Jog or Marathon purchases, reimburses the lesser of 50% (up to $350) or 100% (up to $650) of one verified retake registration fee under the accepted terms. Neither is a promise that you will pass.
Which is cheaper?
TDC sells its MFT course for a one-time fee — check their site for the current price. 1 & Done is a fixed-term program: $250 for one month, $379 for three months, $899 for six months (or $150 per month for six months), and $1,299 for twelve months (or $110 per month for twelve months), with a limited $249 six-month Founding Membership. Neither product auto-renews.
Does 1 & Done offer live coaching?
No. 1 & Done embeds its coaching in the rationales: every answer choice explains why it wins or loses, so the coaching arrives with every question. Therapist Development Center includes access to live coaches as part of its course.
Does 1 & Done have a mobile app?
Not yet. Native 1 & Done apps for iOS and Android are in development. Today the product is web-based and delivers its daily practice questions by text message, so there is nothing to download. Therapist Development Center's course is also web-based.
Can I use both?
Yes, and some candidates do: TDC's coached course for structured content review, and 1 & Done's daily text for rehearsing the first-next-best judgment the exam rewards. The free 1 & Done preview is the fastest way to feel the difference.
