How long does it take to become a Licensed Assistant Behavior Analyst (LaBA) in Missouri?

The BACB requires 1,300 hours of supervised fieldwork for BCaBA certification (or 1,000 concentrated hours with higher supervision intensity). At 40 hours/week full-time, 1,300 hours is roughly 32.5 weeks or about 8 months. With the concentrated pathway, you could finish in as little as 5–6 months if supervision is intensive. Most candidates complete fieldwork and pass the BCaBA exam in 6 months to 1 year after earning their bachelor's degree.

What is the difference between LaBA and LBA in Missouri?

LaBA (Licensed Assistant Behavior Analyst) is for individuals with a bachelor's degree. LBA (Licensed Behavior Analyst) is for individuals with a master's or doctoral degree. LaBA works under continuous supervision of a BCBA; LBA can eventually practice independently. Both require BACB certification (BCaBA for LaBA, BCBA for LBA) and Missouri state licensure.

Can I practice as a LaBA without a BCBA supervisor?

No. A LaBA must remain under the direct supervision of a BCBA in all practice settings. This is different from a fully licensed LBA, which can practice independently. Your BCBA supervisor retains responsibility for your work and must be involved in all client care decisions.

Can I supervise RBTs (Registered Behavior Technicians) as a LaBA?

No. Only BCBAs and BCaBAs may supervise RBTs. As a LaBA, you are not qualified to supervise RBTs. You can supervise RBTs once you have a bachelor's degree in behavior analysis (already satisfied) and receive a separate qualification from the BACB or your employer.

Can I do supervision remotely or via telehealth?

Partial. At least 5% of your fieldwork hours must involve face-to-face real-time observation by your supervisor. The remaining supervision hours can be conducted remotely (video, phone, etc.), but the 5% face-to-face observation component is mandatory.

How much does the BCaBA exam cost, and can I retake it?

BCaBA exam fees are set by the BACB and Pearson VUE (the exam administrator); costs typically range from $250–$350. You can retake the exam as many times as needed. Each attempt requires a separate exam fee. Continue accumulating fieldwork hours and supervisor documentation while preparing for retakes.

What continuing education do I need as a LaBA?

The Missouri Behavior Analyst Advisory Board sets CE requirements by rule. The specific hours and renewal cycle are not detailed in statutes. Additionally, you must complete 2 hours of suicide assessment/treatment/management training as a condition of initial licensure and for each renewal. Contact the board at (573) 526-5804 for current CE requirements.

Can I eventually transition from LaBA to LBA?

Yes, but you would need to earn a master's or doctoral degree in behavior analysis or a related field, complete the additional fieldwork and coursework required for BCBA (vs. BCaBA), pass the BCBA exam, and apply for Missouri LBA licensure. They are separate credentials; LaBA does not automatically lead to LBA.

Varies by BACB pathway

Why This State Is Complex

Missouri assistant behavior analyst licensure mirrors the LBA pathway but with lower hour requirements (~1,300 vs. ~2,000 for LBA). Complexity is moderate due to BACB deference, monthly documentation strictness (5% supervision minimum), and need to coordinate BACB and Missouri requirements. LaBA requires continuous BCBA supervision in all practice settings, adding ongoing administrative coordination.

Key Requirements at a Glance

Bachelor's degree in behavior analysis, psychology, education, or related field with BACB-required undergraduate coursework

Minimum 1,300 hours of supervised fieldwork (or 1,000 concentrated hours) under a BCBA

5% of fieldwork hours per month in supervision (minimum), including at least one face-to-face real-time observation per month

BACB Board Certified Assistant Behavior Analyst (BCaBA) certification required

Supervisor must be BCBA with completed 8-hour BACB Supervisor Training

Monthly fieldwork documentation and supervisor sign-offs required for BACB

2 hours suicide assessment training (Missouri requirement for initial licensure and renewal)

Background check and fingerprinting ($43.05 fee)

Provisional LaBA license valid for 1 year (renewable once at board discretion)

Must remain under direct supervision of BCBA in all practice settings (no independent practice)

Common Pitfalls to Avoid

Confusing LaBA requirements with LBA; LaBA is the assistant-level credential and requires continuous BCBA supervision in practice

Assuming LaBA is a stepping stone to LBA within Missouri; they are separate credentials (LaBA requires bachelor's degree; LBA requires master's/doctorate)

Attempting to supervise RBTs before passing BCaBA exam; you are not yet qualified

Failing to maintain the 5% monthly supervision minimum or not documenting one face-to-face observation per month

Practicing without direct BCBA supervision while holding LaBA (prohibited; must have BCBA oversight in all work)

Missing the 2-hour suicide assessment training requirement before initial licensure

Not understanding the difference between concentrated fieldwork (1,000 hours with higher supervision intensity) vs. standard fieldwork (1,300 hours)
