Optimization & Safety
Keep learning high, not perfect
Growth Tier 8 Strategy
- Sustain daily learning: the cleanest path is children on Anything, not Work.
- Use reading as catch-up: books can top learning back up even when lessons are not the current desire.
- Let work-watching happen naturally: keep class close to kitchen, research, or crafting traffic.
- Use all three boards when teachers are busy: shorter lessons are usually worth the small loss in lesson XP time.
Threat lock is off
Normal mode: include one safe outdoor strip so skydreaming and nature running do not fail.
Desire Coverage Checklist
Radio Talking
Microelectronics unlocks the comms console. Local 1.6 defs put it at 120 steel + 4 components.
Reading Backup
One reachable book is enough to stop dead time. A bookcase is optional, but it keeps books tidy and nearby.
Two Chairs Per Desk
Student plus teacher seating prevents awkward pathing and makes a small room behave like a real class pocket.
Lesson Taking
Desk, boards, reachable teacher, and a child below the learning comfort band are the core ingredients.
Mechanics & Schedules
Why kids ignore desks
Why Kids Do Not Attend Class
Learning below comfort band?
Child on Anything, not Work?
Current desire is Lesson taking?
Desk, boards, chairs, and adult teacher all reachable?
If yes, the child sits and class can start. If no, the AI pivots to another learning desire.
Reading
Radio talking
Work watching
Skydreaming
Teacher Rules Cheat Sheet
Class is fragile when the adult fails one basic condition. Use this before blaming the desk.
Teacher is ready.
If a child is already seated, use right-click on the desk and prioritize teaching to force the adult over.

Mods & Tools (1.6+)
Vanilla first, then timetable mods
Desks vs. XP Trade-Off
3 boards
Three boards are the default answer when you want class to happen quickly and free adults sooner.
Progression: Education
Best pick if you want bells, fixed classes, explicit teacher assignment, and adult study periods.
More Planning Mod (1.6)
Use it when you want perfect 5×6 or hall-adjacent classroom spacing before spending materials.
Schedule Presets (1.6)
Handy when you have several kids and want to stamp out the same Anything-first schedule quickly.
1.6 release and planning changes
The 1.6 release improved performance and planning quality-of-life. That matters here because school rooms benefit from tighter hall layouts, smoother late-game simulation, and cleaner base planning.
1.6 hotfixes and QoL follow-up
The 2025-08 hotfix line focused on stability and general QoL. It did not materially change lesson-taking or classroom stacking behavior.
Progression: Education update
The 2026-03 mod update matters only if you use a bell-driven classroom. Recheck dependencies and lesson-mod overlap after updating modded saves.
Updated for the Biotech classroom loop on the RimWorld 1.6 patch line.
Quick Solution
If the classroom sits empty, fix the loop in this order: research Complex furniture, place a desk with up to three boards, leave kids on Anything, enable Childcare on at least one awake adult, and cover the other learning desires so children have something valid to do between lessons.
What The Game Actually Checks
- Learning AI runs before joy and work: local `SubTrees_Misc.xml` inserts
ThinkNode_Priority_LearnwithJobGiver_Learnbefore the normal joy and work job givers. - Lesson jobs stop when basic needs are about to bite: local C# fail conditions cancel child learning if the pawn is no longer juvenile or will soon need a basic need badly enough.
- Class can roll many skills: local `Skills.xml` wires Biotech lesson interactions for Shooting, Melee, Construction, Mining, Cooking, Plants, Animals, Crafting, Artistic, Medicine, Social, and Intellectual.
Age Gates Worth Planning Around
| Age | Useful shift in the loop | Why it helps school |
|---|---|---|
| 3+ | Basic work becomes available | Real child-learning years begin. This is when your classroom starts earning its keep. |
| 7+ | Handling, cooking, growing, mining, plant cutting, tailoring, crafting, firefighting | Work-watching gets much richer. Put the classroom near busy utility rooms. |
| 10+ | Doctor, construction, art, warden | This is a strong breakpoint for social and construction-focused children. |
| 13+ | Research and smithing unlock; teen stage starts | Teens can watch and participate in deeper work loops while still benefiting from classroom support. |
Research Ladder
- Complex furniture is the first must-have unlock and costs 300 research in local 1.6 defs.
- Microelectronics costs 3000 research and unlocks the comms console, which covers radio talking when lessons are not rolled.
FAQ
Do I need a dedicated room?
A dedicated room is not strictly mandatory, but it is the easiest way to keep paths clean, boards in range, and teachers from wandering through unrelated jobs.
Do multiple desks share the same blackboards?
Yes. One three-board wall can support several nearby desks if each desk is within facility range.
Can I force a lesson?
You cannot force the desire itself, but once a child is seated you can select an adult and use right-click on the desk to prioritize teaching.
Why does learning stall near the top?
Usually one desire is uncovered. Add a book, power a comms console, open a safe outdoor strip, or move the class closer to real work so work-watching triggers naturally.
Can adults study too?
Not in vanilla school mechanics. Use Progression: Education if you want adult training periods and explicit class timetables.
Troubleshooting
Child sits, but nobody teaches
Raise Childcare priority on two adults, confirm the teacher can talk, and watch for food or sleep drops. If a better job keeps stealing the adult, lower competing work or use manual prioritize teaching.
Kids keep running outside during danger
Save a second child zone that includes only bedrooms, dining, classroom, and books. Toggle it during raids, manhunters, or toxic fallout, then switch back once the threat ends.
Teacher keeps teaching the wrong skill
Cancel the current class and re-issue teaching when the child is still seated. Since lesson interactions are skill-specific behind the scenes, rerolling is the cleanest way to chase Social or Intellectual on demand.
Growth looks behind at age 7 or 10
Stop scheduling Work, push reading as catch-up, and make sure at least one supported lesson, one reading option, one outdoor option, and one work-watching route all exist inside the child area.
