The Three PrepAiro Tools Every IB MYP Teacher Should Know: Assessment Generator, Unit Planner & Feedback Writer
MYP teaching runs on three recurring demands: building assessments that meet criterion standards, writing unit plans that satisfy coordinators, and generating feedback for every student across every criterion. Those three tasks can consume 4-20 hours per term in formatting and documentation alone.
Below is a practical walkthrough of PrepAiro's three core tools: how each works, what you configure, what comes out, and where it differs from alternatives.
💡 Key Takeaways
The Assessment Generator enforces correct command terms by level band and knows subject-specific criterion strands. General AI tools cannot replicate this.
The Unit Planner runs a 5-step wizard that ends with a coordinator-ready PDF, including a coverage check for IBO's minimum criterion assessment requirements.
The Feedback Writer reads students' actual PDF submissions before scoring, so two students at the same band get different, quoted feedback.
Beta teachers reported saving 45-90 minutes of formatting per unit plan and reducing a full week of report writing to a review-queue workflow.
The three tools share context: starting in Unit Planner and moving to Assessment Generator or Feedback Writer carries your subject, topic, and criteria automatically.
Assessment Generator
The Assessment Generator produces criterion-tagged MYP questions with complete mark schemes in two steps. It fills an immediate gap: MYP-aligned questions that correctly map to criterion strands and use the right command terms for the achievement level you're targeting.
Step 1: Content Setup
You choose year group (MYP 1-5), subject, and topic in free text — as specific as "Cell division and mitosis" or "Linear equations with one variable." The optional file upload accepts a PDF or PPTX up to 20MB. When you attach one, questions generate from your actual materials, not a generic curriculum model.
Step 2: Question Parameters
Criteria Assessed. Select which criteria to assess (A, B, C, D). The sidebar dynamically displays strand descriptors for your subject — Criterion B in Biology reads "Inquiring and designing," in Mathematics it reads "Investigating patterns." The tool knows the difference and tags questions accordingly.
Level Target. Pick the achievement level band: 1-2, 3-4, 5-6, 7-8, or Mixed. This controls which command terms the generator enforces. A Level 1-2 question will use "State" or "Identify." A Level 7-8 question will use "Evaluate" or "Justify." The command term appears on every question card.
Question Types. MCQ, Short Answer, Extended Response, Data Processing — mix as needed. Set 1-20 questions and difficulty (Any, Easy, Medium, Hard, or Mixed). A free-text field handles additional constraints.
Output and Export
Each question card shows the question stem, criterion tag, command term, achievement level, mark count, and marking notes. Three actions per card: Keep (green border), Edit (inline editor), or New (regenerates only that card, leaving the others untouched).
Once you have three or more questions kept, Test Paper mode unlocks. Export produces two PDFs: a Student version with questions only and a Teacher version with marks, criterion tags, and marking notes. A "Generate Rubric" button carries your parameters directly into the Rubric Maker.
vs. ChatGPT and Competitors
ChatGPT has no model of MYP criterion strands. Ask it for a "Criterion B Biology question at Level 5-6" and it produces something plausible that doesn't reflect the actual strand descriptor or enforce the correct command term. AssessPrep is the closest real competitor but lives inside ManageBac. Without a school subscription, you can't access it. MagicSchool and Knowt have no IB criterion awareness. PrepAiro is available directly to individual teachers.
Unit Planner
The Unit Planner is a 5-step wizard that builds a complete, coordinator-ready MYP unit plan: Statement of Inquiry, inquiry questions by type, summative task, lesson sequence, ATL skills, Learner Profile, differentiation, and criterion coverage. Beta teachers reported saving 45-90 minutes of formatting per unit.
Steps 1-2: Basics and Inquiry Framework
You enter year group, subject, topic, unit duration (4-12 weeks), and periods per week. Subject and year pre-fill from your teaching profile.
In Step 2, the tool pre-selects a Key Concept and Global Context based on your topic — you can override either with dropdowns. Related Concepts are toggleable. The right panel generates three Statement of Inquiry options simultaneously; you select one. Below it, nine inquiry questions appear in IB's required categories: three Factual, three Conceptual, three Debatable. Every item is editable, and "Regenerate" produces a fresh set.
IBO's moderation process checks that inquiry questions align with their defined categories. Teachers who write questions without category awareness often need to rewrite them during coordinator review. The Unit Planner enforces the categorisation from the start.
Step 3: Assessment
The tool pre-fills a summative task title from your topic and selected SOI. You choose the task type (Investigation, Project, Performance, Test, Portfolio, or Presentation) and toggle which criteria (A, B, C, D) the task assesses. A "Generate Questions" button opens the Assessment Generator with your unit context already loaded: subject, year, topic, and criteria carry over.
Step 4: Lesson Sequence
The planner generates a full lesson sequence for your unit duration. For an 8-week unit at 4 periods per week, that's 32 lesson cards. Each card shows lesson number, title, inquiry type tag (Factual, Conceptual, Debatable, or Summative), criteria tags, and duration (50 or 80 minutes). The pedagogical arc follows IB's recommended progression: factual foundation in Weeks 1-2, conceptual connections in Weeks 3-4, critical inquiry in Weeks 5-6, summative preparation in Weeks 7-8. Drag to reorder, remove, or add lessons per week. Each card has a "Plan" button that opens the Lesson Planner with full unit context pre-filled.
Step 5: Review and Export
Before export, the tool runs a coverage check and flags any criterion not assessed in any lesson or summative task. IBO requires each criterion to be assessed at least twice per year. The coverage check surfaces this gap before your coordinator does, particularly for Criterion D, which teachers often assign to the summative task only.
The review panel also shows ATL skills with specific lesson references, Learner Profile attributes, differentiation paragraphs, and a resource list. Export to PDF for coordinator submission or Word for editing flexibility.
vs. Toddle, ManageBac, and ChatGPT
Toddle is school-purchased. PrepAiro is available to individual teachers directly. ManageBac has unit plan templates you fill in manually, with no AI generation. ChatGPT has no model of IBO's 16 Key Concepts, no concept of criterion coverage as a compliance requirement, no GRASPS task structure, and no understanding of inquiry question categories as IB defines them. It can produce text that looks like a unit plan, not a plan that passes coordinator review.
Feedback Writer
The Feedback Writer covers four distinct feedback contexts across an MYP term, each in its own tab: Assessment, Report, Report Season, and Quick Comment.
Assessment Tab: Reading the Actual Submission
Most feedback tools, including SchoolReportAI, IB Genie, MagicSchool, and ChatGPT, generate feedback from a score you type in. They never see what the student wrote. Two students who both score a 5 on Criterion A receive identical comments.
PrepAiro's Assessment tab works differently. You select the student, MYP year, and subject, then upload the student's PDF (up to 20MB). The tool reads the actual submission, evaluates it criterion-by-criterion against the MYP rubric, and returns suggested band scores per criterion, strand-level justification, and direct quotes pulled from the student's text. You review and adjust any scores you disagree with, then confirm. The tool generates student-facing feedback cards that reference what the student actually wrote. Confirmed scores write automatically to the student's criterion history.
Report Tab: End-of-Term Comments
You select the student, subject, reporting period (Term 1, 2, 3, or Full Year), and MYP year, then choose what to include: score trends, specific task references, comparison to last term, ATL skills. Per-criterion scores use steppers on a 0-8 scale. Criteria you didn't assess are greyed out. Tone options: Encouraging, Balanced, Direct, Formal, Warm. Length: Brief, Standard, Detailed. If you've confirmed scores through the Assessment tab, the Report tab pulls from that history automatically.
Report Season Tab: The Full-Class Workflow
MYP teachers typically write 50-125 report comments per term at 5-15 minutes each — 4-20 hours concentrated into a short reporting window. In Report Season, you select your whole class, subject, and reporting period. The tool generates comments for every student simultaneously. You work through a review queue: student name, criterion summary, generated comment, then edit or approve. Teachers describe reducing a full week of report-writing to 1-2 hours of queue review.
Quick Comment Tab
Enter the student's name, year, subject, topic, and per-criterion scores, set tone and length, and the output is four lines, one per criterion, 1-2 sentences each. A "Copy All" button puts it on your clipboard.
Feedback Writer: How It Compares
| Tool | Reads student submission | Strand-level output | IB curriculum structure | Batch class generation |
|---|---|---|---|---|
| PrepAiro | Yes | Yes | Yes | Yes |
| SchoolReportAI | No | No | Partial | No |
| IB Genie | No | No | Surface-level | No |
| MagicSchool | No | No | No | No |
| ChatGPT | No | No | No | No |
How the Three Tools Work Together
The Unit Planner's Step 3 sends your subject, topic, Statement of Inquiry, and selected criteria directly into the Assessment Generator. The Assessment Generator's output includes a "Generate Rubric" button that carries those same parameters into the Rubric Maker. Scores confirmed in the Feedback Writer's Assessment tab write to each student's history, and the Report and Report Season tabs draw on that history automatically. Each tool you use makes the next one faster because context accumulates rather than resetting.
Frequently Asked Questions
Does the Assessment Generator require a past paper subscription?
No. The "Past Papers" and "Both" options in the Question Source field are included in your PrepAiro plan. Past paper content is integrated into the platform directly.
Can I use the Feedback Writer across all my MYP classes?
Yes — no cap on subjects or classes. You select subject and year each time you generate feedback.
What happens to student PDFs I upload?
Uploaded PDFs are processed to generate feedback and not stored permanently. The confirmed scores write to the student's criterion history in your account; the original document is not retained after the session.
If my school has ManageBac, do I still need PrepAiro?
ManageBac handles administrative records and unit plan templates. It doesn't generate questions, build unit plans from your inputs, or read student submissions to produce feedback. PrepAiro runs alongside ManageBac. You export coordinator-ready documents from PrepAiro and submit them wherever your school requires.
How long does the Unit Planner take?
Most teachers complete the full 5-step wizard in 15-25 minutes, including review at each step. The plan is ready to export at the end of Step 5 without additional formatting.
