3 Assessments for Early Learners with Autism: A Guide for BCBAs and ABA Providers

In ABA, assessments for early learners lay the foundation for effective, individualized care. They help BCBAs identify a learner's strengths, areas of need, and motivations, providing the information needed to develop meaningful treatment goals and intervention plans. Assessments also establish a baseline for monitoring progress and measuring outcomes over time.
With so many assessment tools available, choosing the right one can be challenging. In this guide, we'll highlight three of the most commonly used assessments for early learners with autism, exploring what each measures, its key features, and when it may be the best fit for your learner.
What’s an Early Learner?
In ABA, an early learner generally refers to an infant, toddler, or preschool-aged child, typically from birth through age five. Assessment and therapy during the early years should focus on identifying and building the foundational skills that support a positive quality of life, including:
Communication
Social interaction
Play
Learning readiness
Daily living skills
Motor development
Adaptive behavior
Assessments should be developmentally appropriate and designed to identify a learner's current abilities, emerging skills, and areas where additional support may be beneficial.
The Meaningful Outcomes Treatment and Assessment Scale, Early Learner (MOTAS-EL)
The Meaningful Outcomes Treatment and Assessment Scale – Early Learner (MOTAS-EL) is a comprehensive criterion-referenced assessment released in 2026. It was designed specifically for children ages 0–5. Developed as a companion to the original MOTAS, the MOTAS-EL was created to help clinicians assess the unique needs of infants, toddlers, and preschool-aged children.
The MOTAS-EL evaluates nearly 900 skills across 17 developmental domains, including communication, play, social behavior, joint attention, imitation, self-care, safety, community participation, cognitive engagement, and more.
One feature that distinguishes the MOTAS-EL from many other ABA assessments is its emphasis on meaningful, family-centered care. Before completing the assessment, clinicians conduct the Levels of Optimum Performance – Early Learner (LOOP-EL) interview, a structured caregiver interview that identifies the child's strengths, family priorities, and the domains that are most meaningful to target. This helps ensure treatment goals reflect what matters most to the learner and their family as a whole. It also includes the Joy Curriculum to guide caregiver treatment guidance.
While the MOTAS-EL is criterion-referenced, it also includes developmental milestone age ranges for each skill. These milestones provide helpful context about when skills typically emerge, allowing clinicians to determine whether a learner's performance is developmentally expected.
Beyond the assessment itself, the MOTAS-EL includes several supplemental resources that support comprehensive treatment planning, including a School Readiness Checklist, Motor Skills Checklist, MONROE Phonetic Sound Inventory, Sensory Systems & Activities guide, the Joy Curriculum, and the Kindness Method.
Key Features
Developmentally informed
Specifically designed for children ages 0–5
Nearly 900 skills across 17 developmental domains
Includes the LOOP-EL caregiver interview to incorporate family priorities & the Joy Curriculum for caregiver treatment guidance

VB-MAPP (Verbal Behavior Milestones Assessment and Placement Program)
The Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) is one of the most widely used early learner skill-based assessments in ABA. The VB-MAPP is a criterion-referenced assessment, curriculum guide, and skill-tracking system based on B.F. Skinner's analysis of verbal behavior and developmental milestones.
This assessment is designed primarily for toddlers and preschool-aged children, up to age 6. The VB-MAPP evaluates 170 language, learning, and social milestones across three developmental levels that correspond to skills typically acquired between birth and 48 months of age.
The VB-MAPP assesses many of the prerequisite skills needed for learning, including listener responding, motor imitation, play, social skills, classroom readiness, reading, writing, and early academic concepts.
In addition to the Milestones Assessment, the VB-MAPP includes the Barriers Assessment, which identifies factors that may interfere with learning, and the Transition Assessment, which evaluates a learner's readiness for less restrictive environments.
Features
A widely recognized assessment used in ABA
Emphasis on verbal behavior
Includes Milestones, Barriers, and Transition Assessments
Provides a framework for identifying skill deficits and guiding programming

ABLLS-R (Assessment of Basic Language and Learning Skills – Revised)
The Assessment of Basic Language and Learning Skills – Revised (ABLLS-R) is another one of the most commonly used criterion-referenced assessments and skill-tracking systems in ABA and educational settings. The ABLLS-R is designed to evaluate the foundational skills needed for communication, learning, and independence.
Unlike the VB-MAPP, the ABLLS-R provides significantly greater depth across functional skill areas, making it particularly useful for long-term curriculum development and individualized programming. The ABLLS-R provides an in-depth analysis of a learner's abilities across 544 skills in 25 domains. In addition to verbal behavior skills such as requesting, labeling, and intraverbals, the assessment evaluates social interaction, play, classroom readiness, academic readiness, self-help skills, and more.
To simplify the assessment process, the ABLLS-R Skill Acquisition Program Manual can further support clinicians in translating assessment results into individualized intervention plans.
Like the MOTAS-EL and VB-MAPP, the ABLLS-R is criterion-referenced, meaning learners are evaluated against clearly defined skill criteria rather than compared to same-age peers.
Features
Evaluates 544 skills across 25 developmental domains
Covers communication, social, adaptive, academic, and motor skills
Functions as both an assessment and curriculum guide
Widely recognized and accepted within the ABA field

Which Assessment Is Right for Your Learner?
Selecting an assessment depends on the learner’s needs and the clinician’s experience and preferences.
Choose the MOTAS-EL if you're looking for a comprehensive, developmentally appropriate assessment designed for children ages 0–5 with a strong emphasis on meaningful, family-centered care.
Choose the VB-MAPP if your primary focus is verbal behavior and early learning readiness.
Choose the ABLLS-R if you want an assessment for early learners and young children. The ABLLS-R is appropriate for learners up to age 12.
Assessment | Skills | Ages |
MOTAS-EL | 900 skills, 17 domains | Birth–5 |
VB-MAPP | 170 milestones, 3 levels | Birth–6 |
ABLLS-R | 544 skills, 25 domains | Birth-12 |
Final Thoughts
There is no single assessment that is the right fit for every early learner. The best assessment depends on the learner’s developmental level, current skills, treatment goals, and the information a clinician needs to guide programming.
