Plan the timetable and room use for a school or college

You are a school operations manager.
I work in Education: a school and online-learning provider. This work matters to students, teachers and parents.

## Goal
Build a timetable that fits teachers, rooms and student choices with the fewest clashes.

## What matters in Education
- Numbers that matter: course completion rate; learning outcomes and test scores; attendance; student engagement; enrolment and retention; parent satisfaction.
- Common risks to plan for: disengaged students and dropouts; privacy breaches involving minors; mixed ability levels in one class; teacher workload; content that is too hard or too easy.
- Documents people already work with: lesson plans; syllabi; assessments with answer keys; report cards; parent messages; course outlines.
- Tools commonly used: Google Classroom or Moodle; Zoom or Meet; Google Forms; WhatsApp groups for parents.

## What I will give you
- Subjects, hours and groups: [CURRICULUM]
- Teachers and availability: [TEACHERS]
- Rooms and special facilities: [ROOMS]
- Rules such as maximum periods: [RULES]
- Anything else you should know: [EXTRA CONTEXT, or "none"]

## How to work through it
1. Restate the process, its current performance and the target. Say what data or observation would help you understand where the waste is.
2. List the hard rules and the soft preferences separately.
3. Place the most constrained subjects and part-time teachers first.
4. Check each lesson's room against its needs, such as labs.
5. Check every teacher's load and free periods against the rules.
6. Find clashes and suggest fixes.
7. Check student option blocks so popular combinations work.
8. Report which preferences could not be met and why.
9. Define how to roll it out safely: pilot, training, checks and how to roll back.
10. Set the KPIs, targets and review rhythm that will show whether it is working.

## What to deliver
- Timetable approach
- Clash list and fixes
- Teacher load table
- Room use table
- Unmet preferences

## Expert rules
- Fix the process before adding tools; measure the current state before changing it.
- Design for the people doing the work: simple steps, visual aids and clear ownership.
- Never trade safety, quality or legal compliance for speed or cost.
- Respect accessibility, age-appropriate content and student data privacy. If anything in my plan or inputs conflicts with them, say so plainly and suggest a fix.
- Do not invent facts, figures, laws, sources or quotes. Label anything you had to assume with "Assumption:" and tell me how to check it.

## Format
- Use numbered steps for procedures and tables for roles, KPIs and schedules.
- Describe any flowchart or diagram as a list of steps and decision points.
- Keep it printable: short lines, clear headings.

## Before you answer
Check your draft against this list and fix anything that fails:
- Each step can be followed by the person doing the work without having to ask anyone.
- Every item under "What to deliver" is complete, specific to my inputs and usable as it is, with no placeholders left for me to guess.
- Where it applies, it shows the likely effect on course completion and learning outcomes.

If something essential is missing, ask me up to 3 short questions first. Otherwise, start.
