BT vs RBT: what a behavior technician needs in New Mexico

Only in some situations. See the detail below.

As of 2026-10-21, New Mexico Medicaid (MAD Supplement 22-02) describes a 'non-certified behavior technician' pathway that may allow a technician to deliver ABA Stage 3 services for a limited time if all of the following apply: at least 18 years old; high school diploma or equivalent; passed a New Mexico criminal background registry check; completed at least 4 hours of ASD training (prevalence, etiology, core symptoms, characteristics, learning differences) before rendering services; completed at least 20 hours of credential-related training before rendering ABA services; within 90 calendar days of approval completed the 40 hours of BACB-approved-trainer ABA training; and within 180 calendar days completed the prerequisites for a certification test date (e.g. competency assessment, documentation). The 2022 definition then requires the technician to earn certification within the first continuous six months of approval, or stop rendering Stage 2/3 services until certified. However, the same supplement (section 3.11.1) measures the six months from the first date of billing rather than from approval, so the starting point of the deadline is internally inconsistent. The state plan (SPA NM-24-0008) also recognizes another technician credential, the QABA Applied Behavior Analysis Technician (ABAT), so the credential is not limited to RBT or BCAT. That plan separately retains a documented-training pathway that does not require RBT credentials; its silence about deadlines does not prove the supplement's deadlines were repealed. The non-certified BT attestation template was still listed on the HCA site with an October 16, 2024 date (verified via the legacy hsd.state.nm.us copy of the page); the attestation PDF itself and whether the deadlines are currently enforced were not verified. How MCOs treat this window in practice was not verified.

• Age 18 or older (MAD Supplement 22-02)
• High school diploma or equivalent (MAD Supplement 22-02)
• Successful New Mexico criminal background registry check (MAD Supplement 22-02; 8.321.2.12 NMAC says all providers must complete one)
• At least 4 hours of ASD training before rendering Stage 2/3 services (MAD Supplement 22-02)
• At least 20 hours of credential-related training before rendering ABA services, and 40 hours of BACB-approved-trainer ABA training within 90 days (MAD Supplement 22-02)
• Certification (RBT, BCAT, or another credential recognized in the state plan such as ABAT) within six continuous months, measured from approval or from first billing depending on the provision; timing unresolved (MAD Supplement 22-02; SPA NM-24-0008)

Current rule citation is 8.321.2.13 NMAC (effective 12/10/2024), which replaced 8.321.2.12 NMAC (section .12 now concerns youth residential treatment). The three-stage structure remains supported: Stage 1 evaluation by Autism Evaluation Practitioners; Stage 2 (assessment/treatment plan) by a BA (BACB-qualified psychologist, BCBA/BCBA-D, Mentored BCBA); BCaBAs assist supervising BAs, and technicians assist Stage 2; Stage 3 treatment is implemented by technicians under supervision. Per MAD Supplement 22-02 (2022-01-27), Stage 3 practitioners include BACB Registered Behavior Technicians (RBT), BICC Board Certified Autism Technicians (BCAT), and non-certified behavior technicians (time limited). CMS approved SPA NM-24-0008 on December 9, 2024 (effective October 1, 2024), which adds Qualified Applied Behavioral Analyst Board (QABA) and ABAT eligibility, so the credential list in the 2022 supplement is outdated. Services are rendered through an enrolled ABA provider agency; rendering eligibility does not by itself establish independent billing authority. All providers must complete a criminal background registry check.

It depends. See the condition below.

Per the 2022 supplement, technicians may start as a 'non-certified behavior technician' only for a limited time: must hold the RBT or BCAT certificate within the first continuous six months of approval; if not certified in time they must not render ABA Stage 2 or 3 services until certified. After that period a recognized technician certification is required. The 2024 SPA adds QABA/ABAT eligibility, so the current list of accepted technician credentials should be confirmed with HCA.
