40 definitions covering hour types, supervision rules, compliance requirements, certification pathways, and more. No jargon, no guesswork.

Certification

2027+ Standards

The updated BACB fieldwork requirements based on the 6th edition task list. Key changes include higher monthly hour caps (160), duration-based observation requirements, elimination of contact requirements, and adjusted supervision percentages for some pathways.

Documentation

Audit Trail

A chronological record of all changes made to fieldwork data, including who made each change, when it was made, and what the before/after values were. Essential for data integrity and BACB verification.

Certification

BACB

Behavior Analyst Certification Board. The credentialing body that establishes the standards, requirements, and ethical guidelines for behavior analyst certifications including BCBA, BCaBA, and RBT.

Certification

BACB Task List

The official document published by the BACB that outlines the skills and competencies required for certification. The task list defines what unrestricted and restricted activities include and is updated periodically (most recently in 2027).

Certification

BCaBA

Board Certified Assistant Behavior Analyst. The mid-level certification from the BACB for professionals who practice under the supervision of a BCBA. Requires a bachelor's degree and fewer fieldwork hours than the BCBA.

Certification

BCBA

Board Certified Behavior Analyst. The advanced-level certification from the BACB for professionals who independently practice behavior analysis. Requires a graduate degree, fieldwork hours (2,000 supervised or 1,500 concentrated), and passing a certification exam.

Certification

Certification Pathway

The specific combination of certification type (BCBA or BCaBA), standards year (pre-2027 or 2027+), and fieldwork type (supervised or concentrated) that defines a candidate's requirements. There are 8 possible pathways.

Hour Types

Concentrated Fieldwork

A fieldwork type with a reduced total hour requirement (1,500 for BCBA, 1,000 or 800 for BCaBA) but higher monthly intensity and stricter supervision percentage requirements.

Compliance Rules

Contact Requirement

The minimum number of supervision contacts required per month under 2022 standards. Supervised fieldwork requires 4 contacts per month; concentrated requires 6. This requirement was eliminated in the 2027 standards.

Compliance Rules

Fieldwork Compliance

The state of meeting all BACB fieldwork requirements simultaneously, including supervision percentages, hour caps and minimums, unrestricted ratios, observation requirements, and contact requirements for your specific certification pathway.

Documentation

Fieldwork Documentation

The complete set of records, logs, summaries, and forms required to verify and submit your fieldwork experience to the BACB. Includes fieldwork logs, monthly summaries, supervisor contracts, and verification forms.

Documentation

Fieldwork Log

A detailed record of fieldwork hours logged over time, typically including dates, durations, activity types (unrestricted/restricted), supervision details, and supervisor signatures.

Roles

Fieldwork Trainee

A candidate actively accruing fieldwork hours toward BCBA or BCaBA certification under the supervision of a qualified supervisor. Also referred to as a supervisee in the context of the supervisory relationship.

Certification

Fieldwork Verification

The process by which the BACB confirms that a candidate's fieldwork meets all requirements. This may include reviewing documentation, verifying supervisor credentials, and auditing hour logs.

Documentation

Final Fieldwork Report

A comprehensive document summarizing your entire fieldwork experience, including cumulative hours, compliance across all metrics, supervisor attestation, and all required signatures for BACB submission.

Supervision

Group Supervision

A supervision format where a qualified supervisor meets with multiple trainees simultaneously. Group supervision is capped at 50% of total supervised hours to ensure each trainee receives adequate individualized attention.

Compliance Rules

Group Supervision Cap

The maximum proportion of supervised hours that can come from group supervision sessions. Across all BACB pathways, group supervision is capped at 50% of total supervised hours.

Hour Types

Group Supervision Hours

Supervised hours conducted in a group setting with multiple trainees present. These hours count toward your supervision total but are capped at a maximum percentage of your total supervised hours.

Hour Types

Independent Fieldwork

Fieldwork hours accrued while working independently, without a supervisor physically present. These hours still count toward your total but must meet supervision percentage requirements when combined with supervised hours.

Hour Types

Individual Supervision Hours

Supervised hours conducted one-on-one between a trainee and their qualified supervisor. These hours have no cap and are the primary way to meet supervision percentage requirements.

Compliance Rules

Monthly Hour Cap

The maximum number of fieldwork hours that can be counted in a single month. Pre-2027 standards cap at 130 hours per month; 2027+ standards increase the cap to 160 hours per month.

Compliance Rules

Monthly Hour Minimum

The minimum number of fieldwork hours that must be logged in any month where fieldwork is claimed. The BACB requires at least 20 hours per month across all pathways.

Documentation

Monthly Summary

A period-level overview of fieldwork activity showing total hours, supervision hours, activity type breakdown, compliance status, and observation/contact counts for a single month.

Supervision

Observation

A supervision activity where a qualified supervisor directly watches a trainee deliver services to a client. Observations have specific minimum requirements that differ between 2022 and 2027 standards.

Compliance Rules

Observation Requirement

The minimum observation activity required per supervision period. Under 2022 standards, this is count-based (number of observations). Under 2027 standards, it is duration-based (60-90 minutes minimum per period).

Supervision

Observation with Client

A specific type of observation where the supervisor watches the trainee interact directly with a client during service delivery. This is the most common and most valued form of observation.

Certification

Pre-2027 Standards

The set of BACB fieldwork requirements based on the 5th edition task list, applicable to candidates who began fieldwork before the 2027 standards took effect. Features monthly hour caps of 130, count-based observations, and required supervision contacts.

Roles

Qualified Supervisor

A BCBA or other BACB-approved professional who meets specific requirements to supervise fieldwork trainees. They are responsible for oversight, observation, and attestation of a trainee's fieldwork hours.

Roles

RBT

Registered Behavior Technician. A paraprofessional certification from the BACB for individuals who implement behavior analysis services under the supervision of a BCBA or BCaBA. Many RBTs pursue BCBA/BCaBA certification.

Hour Types

Restricted Activities

Fieldwork activities that are related to behavior analysis but are not direct client-facing services. These include administrative tasks, attending workshops, and other supportive activities that are capped at a percentage of total hours.

Hour Types

Supervised Fieldwork

A fieldwork type requiring a minimum of 2,000 hours (BCBA) or 1,300 hours (BCaBA) completed over an extended period with lower monthly intensity requirements. This is one of two fieldwork type options alongside concentrated fieldwork.

Roles

Supervisee

An individual receiving supervision from a qualified supervisor as part of their BACB certification fieldwork requirements. This is the formal term used in the supervisory relationship context.

Supervision

Supervision Contact

A scheduled interaction between a trainee and their qualified supervisor that counts toward meeting minimum supervision contact requirements. Under 2022 standards, a minimum number of contacts per month is required.

Compliance Rules

Supervision Minimum Percentage

The minimum percentage of total fieldwork hours that must be conducted under direct supervision. This percentage varies by fieldwork type: 5% for supervised fieldwork, 10% for concentrated (pre-2027), and 7.5% for 2027 BCaBA concentrated.

Supervision

Supervision Percentage

The ratio of supervised hours to total fieldwork hours, expressed as a percentage. The BACB sets minimum supervision percentages that vary by fieldwork type and standards year.

Supervision

Supervision Period

The defined time frame (typically monthly) over which supervision requirements are measured. Compliance rules like minimum contacts, observation requirements, and hour caps are evaluated per supervision period.

Supervision

Supervisory Relationship

The formal, documented relationship between a fieldwork trainee and their qualified supervisor. This relationship must be established before fieldwork hours can be counted and typically involves a written agreement.

Hour Types

Total Fieldwork Hours

The cumulative number of fieldwork hours a candidate must complete for certification. This total varies by certification type (BCBA/BCaBA), fieldwork type (supervised/concentrated), and which standards apply.

Hour Types

Unrestricted Activities

Fieldwork activities that directly relate to behavior analysis practice and are not limited in the proportion of hours they can represent. These typically include client-facing services like assessments, skill acquisition programs, and behavior reduction procedures.

Compliance Rules

Unrestricted Hour Ratio

The cumulative percentage of total fieldwork hours that must come from unrestricted activities. BCBA candidates need at least 60% unrestricted; BCaBA candidates need at least 40%.
