ABA Assessments: Understanding Behavior Through Analysis

Understanding ABA Assessments

As you know, ABA is a scientific discipline that aims to understand and improve socially significant behaviors through the application of learning principles. Assessments used in ABA play a crucial role in this process by providing valuable insights into the function, context, and determinants of behaviors.

By gathering data, analyzing patterns, and identifying target behaviors, ABA professionals can develop individualized education plans.

Types of ABA Assessments

When it comes to conducting behavior assessments used in ABA, choosing the right assessment is crucial. The assessments should align with the learner’s age, developmental level, and specific needs. Let’s explore some common assessments used in ABA and their purposes:

1. Early Start Denver Model (ESDM)

The ESDM assessment is designed for learners aged 12-48 months. It focuses on early developmental goals such as joint attention, eye contact, pointing, and beginner receptive skills.

By targeting foundational skills, the ESDM sets the stage for future learning and skill development.

2. Verbal Behavior Milestones Assessment Placement Program (VB-MAPP)

The VB-MAPP is an age-normed assessment that tracks language, learning, and social skills. It evaluates the learner’s abilities across various domains, including manding (requesting), tacting (labeling), listener responding, social behavior, and play skills.

The VB-MAPP provides a comprehensive overview of the learner’s current skill set.

3. Assessment of Basic Language and Learning Skills – Revised (ABLLS-R)

The ABLLS-R is a thorough assessment tool used to track the progress of basic linguistic and functional skills. Unlike the VB-MAPP, the ABLLS-R breaks down each language component into smaller, more specific skills.

This detailed approach helps identify specific areas of strength and areas that require further development.

4. Promoting the Emergence of Advanced Knowledge (PEAK)

The PEAK assessment is another age-normed assessment that evaluates language and cognition skills. It identifies areas of strength and areas of improvement, providing valuable insights into the learner’s abilities and challenges. The PEAK assessment covers various skills, including receptive language, expressive language, conversation skills, and problem-solving.

Choosing the most appropriate assessment depends on several factors — including the learner’s age, current skills, and intervention goals. A qualified ABA professional will consider these factors and select the assessment that best aligns with the learner’s needs.

A Note About Programming to Assessments

Here’s a note of caution: ABA assessments are exactly what they state; they’re just assessments.

Assessments are great for assessing skills, but should not become curricula. Assessments can be used to guide programming, but should never be the be-all and end-all of your programming.

Every individual is unique, so your ABA programming should be individualized to meet learners’ needs. That means: be sure to stay away from cookie-cutter programs.

Conducting ABA Assessments

The process of conducting ABA assessments involves several key steps:

Collecting Data

ABA professionals collect data through direct observation, interviews, questionnaires, and reviewing records. Data collection helps establish a baseline and provides a comprehensive understanding of the behaviors.

Identifying Target Behaviors or Skills

Based on the purpose of the assessment, specific target behaviors or skills are identified for assessment. These targets guide the selection of appropriate assessment tools and methods.

Choosing Assessment Tools and Methods

A variety of assessment tools and methods are available, including direct observation, checklists, rating scales, and interviews. Selection is based on the individual’s characteristics and goals of the assessment.

Observational Techniques

ABA professionals use systematic and structured observational techniques to gather data on behaviors, antecedents, consequences, and environmental factors. This information aids in understanding behavior patterns and developing effective plans.

 

Analyzing and Interpreting ABA Assessment Results

Once the assessment is complete, ABA professionals analyze and interpret the collected data:

Data Analysis

Data is analyzed to identify patterns, trends, and correlations among behaviors, antecedents, consequences, and environmental factors. This analysis helps in developing hypotheses and identifying potential education strategies.

Generating Hypotheses

Hypotheses are formulated to explain the relationships between behaviors and their underlying causes. These hypotheses guide the development of behavior-learning strategies.

Developing Better Plans

Based on the assessment results and hypotheses, ABA professionals create plans that outline strategies for addressing target behaviors, teaching new skills, and promoting positive behaviors.

Collaboration and Communication with Parent Support

ABA professionals collaborate with individuals, families, caregivers, and other professionals involved in the individual’s care. Regular communication ensures a comprehensive and coordinated approach to educating the client.

Benefits of ABA Assessments

Assessments used in ABA offer several benefits in understanding and addressing behaviors:

Individualized Programs

ABA assessments provide a comprehensive understanding of an individual’s behaviors and skills. They can guide programming, but they should not be used as a curriculum.

Stay away from programming directly to assessments. Instead, use assessments to develop appropriate programs that are individualized to the clients’ needs, and tailored to their unique strengths.

Monitoring Progress and Making Data-Driven Decisions

Regular assessment allows for ongoing progress monitoring, making adjustments to intervention strategies based on data analysis, and ensuring the effectiveness of education plans.

Challenges & Considerations in ABA Assessments

While ABA assessments are a valuable tool, they come with their own challenges:

Addressing Individual Differences and Unique Needs

ABA professionals must recognize and accommodate individual differences and varying levels of skill when conducting assessments and developing education plans.

Ensuring Validity and Reliability

ABA assessments must be valid and reliable. Validity ensures that the assessments measure what they intend to measure, while reliability ensures consistency and accuracy in the assessment results.

Continuous Professional Development

ABA professionals should engage in ongoing professional development to stay updated with the latest assessment tools, techniques, and research findings. This helps maintain the effectiveness and quality of their assessments.

Collaboration and Communication

Effective collaboration and communication with individuals, families, caregivers, and other professionals involved in the assessment process are crucial for obtaining accurate information and developing comprehensive education plans.

Time and Resources

Conducting thorough ABA assessments requires time, resources, and expertise. ABA professionals must allocate sufficient time and utilize appropriate resources to ensure the quality and accuracy of assessments.


ABA assessments play a vital role in understanding behaviors, developing effective programs, and improving individual outcomes. By utilizing various assessment tools and methods, collecting data, and analyzing results, ABA professionals can gain valuable insights into skill strengths and deficits. In turn, this will provide valuable information needed to develop individualized education plans.

While challenges exist, promoting collaboration and celebrating individual differences can enhance the effectiveness and impact of ABA assessments.

  2. Have you looked at potentially running through the other ADL assessments such as socially savvy, AFLS, or EFLS? Or looking into more posts about pre-requisites for different functional living and vocational skills??

    1. Great suggestion! We can definitely talk about those assessments too! We will add it to the list of topics to cover – thank you!

    1. There are many assessments available for purchase online – depending on the need of your client, you can do a quick search engine search to find what you need!

  3. I was wondering about reassessments. When having to update and reassess a client who was a previous BCBA, who used different reassessment tools then you do and not age appropriate, is it ok to change this? The client was 5 at time of assessment and she only did afls.
