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.

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.

Pricing, plainly

  • The Sprint — $379 for 3 months
  • The Jog — $899 for 6 months, or $150/month × 6
  • The Marathon — $1,299 for 12 months, or $110/month × 12
  • Founding Membership — $249 for 6 months, limited to the first 25 qualifying purchases

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.
