Constraint-aware randomization
Separation and pairing that actually works
Paste lists of students who shouldn't sit together (behavior, testing, IEP) and lists who should be adjacent (peer tutoring, ELL, SEL). The shuffler respects both sets of constraints across up to 50 attempts.
Separate-these constraints (don't seat adjacent)
Keep-together constraints (seat adjacent)
50-attempt satisfaction with graceful fallback
Re-shuffle infinitely until the chart feels right

About this tool
The classroom seating chart generator built for 40-student classes
Forty students is the oversized-section case — combined electives, PE blocks, large lecture classes, after-school tutoring cohorts, and some high-enrollment urban districts. At this size, layout choice is constrained by furniture and safe egress paths, not pedagogy. The generator handles 8×5, 10×4, and eight groups of five, with constraint support across every layout so separation and keep-together pairs persist when you re-seat.
The three layouts 40 students actually fit into
8×5 grid (eight across, five deep) is wide — works in a lecture-hall setup or a classroom with the desks pushed against the walls. 10×4 is the opposite — deep and narrow, common when the room has a clear center aisle. Eight groups of five is the lab/station-rotation default. 4×10 (four across, ten deep) is the rarest layout but works for rooms with a single narrow footprint. Pick the layout that matches the room, then worry about pedagogy.

10×4 grid (deep room, center aisle)
Eight groups of five (station rotation, lab)
Double U-shape (rare but possible for seminar)
Safety and egress at 40
Classrooms built for 30 that seat 40 are a fire-code risk. Before finalizing any layout, ensure a 36-inch aisle to both exits and a clear path to the door nearest the room's windows (the secondary evacuation route). The generator doesn't model furniture dimensions — but the printed chart is a visual tool you can overlay on your room's floor plan to validate.
Why group work is the rescue at 40
Direct instruction to 40 students is a lecture. The only way to preserve engagement is aggressive group work — eight groups of five, with clear roles within each group (facilitator, recorder, presenter, challenger, checker). The generator's keep-together constraint lets you anchor each group around a known leader, then randomize the rest. Re-shuffle weekly to prevent cliques and broaden collaboration.
Printing and managing the chart
An 8×5 chart fits on a single landscape page at 12pt — readable but tight. Print at legal size (8.5×14) for a more comfortable 14pt. For the sub folder, include a second page with the eight group assignments in a table format — easier to take attendance from than a 40-seat grid. All client-side; no uploads, no saved rosters.

Loved by Educators
Hear from teachers who are saving time and providing better feedback.
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”
“More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.”
“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”
“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”
“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”
“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”

It's above the US median and above most research-based recommendations for optimal learning. But it's the reality for many high-school electives and PE classes. A deliberate seating chart with aggressive group work and weekly rotation mitigates some of the engagement loss at scale.
