PEAK Relational Training System

Promoting Emergence of Advanced Knowledge, PEAK is an extensively researched, clinically versatile and empirically supported assessment tool that takes traditional ABA assessments to a new level by assessing and training for equivalences and relational learning. The PEAK Comprehensive Assessment is the only standardized assessment in the ABA world and focuses primarily on expressive and receptive language skills that range from basic single sound utterances to complex cognition proficiencies such as abstract induction and deduction. Use of the PEAK assessment and curriculum has been shown to have an impact on reducing challenging behaviours and increasing IQ.

Centre-Based Clinical Services (Ages 18 months – 18 years)

Our Centre based services take place at the New Leaf Centre, conveniently located at the corner of Montrose Rd and Thorold Stone Rd in Niagara Falls.

Our in-centre services use the principles of ABA to work on increasing your child’s skills and decreasing challenging behaviour, if needed.  At New Leaf, we customize each child’s programming to capitalize on their unique strengths and help bridge the gap between their current skills and where they need to be. We focus on the entire child, with emphasis placed on learning functional, adaptive skills in a fun and supportive environment.

We use 1:1 teaching and small group intervention to work on specific skills with your child.

At New Leaf, we use ABA to improve:

  • Social skills
  • Language and communication
  • Motor skills
  • Activities of daily living
  • Academics
  • Challenging behaviour

Within each of these broad domains, we use a combination of assessment results and parent input to select individualized goals geared to the specific skill gaps of your child.

All ABA programs qualify for MCCSS funding and are overseen by a Board Certified Behaviour Analyst (BCBA) to ensure highly quality programming and implementation with your child.

Our in-centre services are offered in 12-week blocks, with sessions running either 3 hours or 4 hours in length.

Morning session times are 9am -12pm or 8:30am – 12:30pm

Afternoon session times are 1 – 4pm or 1 – 5pm

We also offer extended hours for those families with a busy schedule, and can accommodate before and after session care if your family requires it!

All children will have an initial intake assessment prior to starting services, or prior to restarting services after more than 12 weeks away from service.

We are currently registering children for January 4, 2021 (with assessments being completed in December 2020).

Assessment Services

Our assessment services are individualized just like all of our services. This means that the assessment used for your child is not a blanket approach and is instead selected based on the clinical tool that would be most suitable to their current skill repertoire. Often a combination of assessments are used and the results of these assessments are used to guide your child’s instructional design and intervention.
Some of the assessments we use include:

  • Early Start Denver Model (ESDM)
    • Ages: 0-3 years
    • Focuses on skills that are specific to the domains associated with a diagnosis of ASD

    • Language based assessment that aims to improve the core foundational verbal behaviour skills as well as higher level cognition skills that ensure a child is able to learn rather than using rote/memorized responses
  • Verbal Behaviour-Milestones Assessment and Placement Program (VB-MAPP) or The Assessment of Basic Language and Learning Skills - Revised (ABLLS-R)
    • Ages: 0-4 (or 5)

    • Ages: All.
    • Addresses the potential environmental factors which may be maintaining a challenging/maladaptive behaviour.
    • Results from this process allow clinicians to implement functionally equivalent and appropriate alternatives to the challenging behaviour.
    • Utilizes both direct and indirect methods of assessment such as direct observations, data collection and analysis, questionnaires and environmental manipulations.
  • Individualized Assessment and Instructional Design:

    • Regardless of the assessment that is determined to be the most appropriate based on age, skill level and goals, each person also gets an individualized assessment of their skills, progress and unique learning preferences and trajectory.

Board Certified Behaviour Analyst (BCBA) Supervision

In order to ensure that our clinicians are providing your child with high quality care, all of our staff receive supervision from a BCBA as part of their employment. This includes those seeking BACB hours to write the exam and RBTs maintaining or seeking certification.

We offer remote supervision to those requiring clinical oversight who do not have access to a BCBA in their current employment setting.

Available for RBTs looking to maintain certification, individuals accruing BACB hours to write their exam as well as to organizations requiring clinical oversight by a BCBA.

If you are interested in a school placement, please click here.


We offer after-school tutoring for those students that are struggling in specific academic areas.  Our ability to break down learning into smaller, more understandable pieces of information, as well as to understand where learning gaps are, means that children not only get their work done, but they also understand what they are doing and how to do it independently.

Ages: 7-13

Drop-In Nights

These nights are first-come, first-serve and are open to anyone meeting the prerequisite criteria.

Registration is required and there is a small fee for these events (this fee is not covered by Ministry funding at this time).

The purpose of drop-in nights is to have fun and meet peers (this is not a clinical service although ABA strategies are incorporated into the evening.

Check our Facebook or Instagram page for any upcoming drop-in nights and themes and register online.

Our Intake Process

All of our services require an initial intake/assessment of the individual attending services (this applies to individual services).

The intake will be scheduled at the centre and will allow our clinicians to assess current skills and abilities as well as any potential barriers to learning such as challenging behaviours.

Based on the results of the initial assessment it will be determined which subsequent assessment would be most appropriate as well as intensity of service and group suitability.

The results of the intake are communicated with the family and a report is provided summarizing the measures used and results. Due to COVID and our limit on visitors into the centre, a phone follow-up is available for those families who wish to further discuss their Childs results.

Prior to intake, we request background information and input from parents/caregivers on goals for their child and do our best to assess these during our intake process.

Do you have a waitlist?

We do have a waitlist at this time. We do have some popular session times but we do our best to accommodate each family’s schedule.

Are your services covered by the Ministry funding I received?

Our ABA services are covered by Ministry funding.

What are your Covid-19 safety protocols?
  • cleaning with Health Canada approved anti-viral cleaning products between every session
  • Limiting centre access to only children and staff
  • One child per room with 1 instructor
  • Mask wearing for all adults, and for those children that can tolerate it
  • Covid-19 screening and temperature checks for all those who enter our centre

Once the intake assessment has been completed, families will receive an intake report detailing the results, typically within 2-3 weeks. At that time, we are ready to schedule sessions and prepare to start ABA!

At this time, we can typically start working with a new family within 6 weeks of the initial booking of the assessment.
