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 7-day free trial — no payment is required until the trial ends.
The three tiers for instructors are:
- Family (€8/mo): Designed for parents running home practice. Supports one learner and allows cloning and modifying template programs.
- Professional (€18/mo): Designed for instructors and clinicians. Supports up to three students, includes full analytics and BKT mastery tracking.
- Researcher (€60/mo): Full access including the Varela Transfer Matrix, custom relational frame dimensions, raw data export, and unlimited students.
If you are a clinician, start with the Professional tier. You can upgrade to Researcher later if you need the advanced features.
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: Browse and Clone a Template Module
Click Modules in the sidebar. You will see the Templates tab, which contains pre-built curriculum programs ready to use.
The recommended starting point is the Complete MTS Progression template — a structured sequence of 8 exercises covering all four MTS levels (identity, non-identical, symbolic, and auditory matching). It is designed for children beginning formal MTS training.
To use a template:
- Click the template card to see its details.
- Click Clone to My Modules.
- The cloned program now appears in the My Modules tab, where you can edit it.
You do not have to use the template as-is. Once cloned, you can add, remove, or reorder exercises, change mastery criteria, or adjust the stimulus set for your particular student.
Step 4: Assign the Program and Run Your First Session
Navigate to your student’s profile (click their name in the student list). Click Assign Program and select the program you just cloned. Once assigned, the program appears in the student’s assigned programs.
To start a session:
- Click Start Session next to the program.
- The system switches to the student-facing interface — the screen your learner will see.
- Trials begin automatically. Select the correct comparison stimulus to continue.
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.
