This guide walks you through everything you need to run your first session in INTERLAZA — from creating your account to reviewing your first set of results. It assumes no prior experience with the platform, but does assume familiarity with basic behavioral terminology and match-to-sample procedures.
Step 1: Create Your Account and Choose a Tier
Navigate to interlaza.app and create an account. You will be asked to choose a subscription tier. All paid tiers include a 14-day free trial — no payment is required until the trial ends.
The three tiers for instructors are:
- Family: Designed for parents running home practice. One learner, with the guided pathway and the Today screen — each day’s session comes already prepared.
- Professional: Designed for instructors working with several learners. Multiple learners, full analytics, and BKT mastery tracking.
- Researcher: Full access including the Varela Transfer Matrix, custom relational frame dimensions, and raw data export.
If you are a practicing instructor, start with the Professional tier. You can upgrade to Researcher later if you need the advanced features. See the pricing page for current plans.
Step 2: Set Up Your First Student Profile
After completing the onboarding wizard, you will land on the main dashboard. Click Students in the sidebar, then Add Student.
Fill in the student’s name and any relevant details (school, grade, geographic information for research purposes). You can also set an avatar color — a small personalization that makes it easier to distinguish students at a glance in the student list.
Once the profile is saved, the student appears in your student list. All subsequent programs, sessions, and mastery data are stored under this profile.
Step 3: Choose a Route on the Pathways Screen
Click Pathways in the sidebar and open Teach a child. The routes are presented as a ladder, in the order they are meant to be used — and you can enter wherever your child already is:
The recommended starting point is the Interlaza route (33 stages): it teaches relating, not just recognising — from matching identical images through same colour, size, function and part-and-whole to real-world relations, with no-correction probe stages along the way to check that the child learned the relation rather than the particular pair. If the basics are missing, the Vocabulary route (23 stages) builds them first; RFT Foundations and Sidman Equivalence come after.
There is nothing to configure before starting: every stage carries its exercise type, mastery criteria and materials.
Step 4: Enroll the Student and Run Your First Session
Open your student’s profile and their Pathways tab, then enroll them in the route you chose. The route’s card shows which stage the child is on, and Start Practice sits on that same card — the screen switches to the student-facing interface and trials begin automatically.
During the session, each trial presents a sample stimulus and two or more comparison stimuli. Correct responses are followed by animated feedback. Incorrect responses restart the trial. The errorless learning system ensures that early trials are easier than later ones — distractors start faint and become progressively more visible as accuracy improves.
Step 5: Review the Results
After completing or ending a session (tap the back arrow on the session screen), you are returned to the results view. This screen shows:
- Per-concept accuracy: How many trials each concept appeared in and how many were correct.
- Mastery status: Which concepts are in progress, approaching mastery, or mastered based on BKT probability estimates.
- Session timeline: A visual representation of accuracy across the session.
- Adaptive adjustments: Any changes the system made automatically (distractor count increases or decreases).
If your student had any intervention alerts during the session — position bias, fast guessing, or other patterns — they appear at the top of the results screen with a brief explanation and suggested follow-up actions.
Understanding BKT Mastery Indicators
Each concept in a student’s program has a mastery indicator. The indicator shows:
- In progress (gray): The system does not yet have enough data to estimate mastery reliably.
- Learning (amber): P(mastery) is rising but has not yet crossed the mastery threshold (0.95 by default).
- Mastered (green): P(mastery) ≥ 0.95, confirmed over at least two sessions.
Once a concept reaches “Mastered” status, the system will still include it in sessions occasionally — maintenance probes ensure that mastery is retained over time, not just achieved once.
Next Steps
Once you are comfortable with the basic workflow, explore the more advanced features:
- Exercise types: Beyond the four MTS levels, INTERLAZA supports equivalence training, relational frame exercises, contextual control, and generalization probes. Each is configurable and tier-appropriate.
- Errorless learning settings: The default errorless procedure uses distractor opacity fading. You can switch to size, highlighting, arrow, or position-based prompts for students who respond better to different prompt types.
- Supervision mode: If you have a supervisor or are a supervisor yourself, the supervision module lets a second person observe a live session remotely, attach notes to specific trials, and review the session after the fact.
