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

Layouts teachers actually use
Rows, groups, U-shape, pairs, band, testing mode
Four base layouts cover most classrooms. Adjust seats-per-row to match your room. The rendered chart is print-ready — tape it inside your gradebook or hand it to a substitute.

About this tool
The classroom seating chart generator built for 30-student classes
Thirty students is the modal US public-school class size, and the arrangement puzzle everyone asks about first. A 5×6 or 6×5 grid, six groups of five, or a U-shape with two inner rows all fit cleanly. The generator produces every layout from a single paste, and re-shuffles instantly — useful when day-one attendance shifts the roster by two or three names. Constraints persist across layouts so you can swap from rows (direct instruction) to groups (collaborative task) without re-entering who shouldn't sit together.
The three layouts teachers ask about most
5×6 rows (five across, six deep) is the standard — front-to-back aisles for sub plans and a clean row-based call-and-response pattern. Six groups of five works for literature circles, lab groups, and station rotations. U-shape with inner rows gives seminar sight lines while still seating 30 — not every classroom has the footprint, but for rooms that do, it's the highest-engagement arrangement. Pick the one that matches today's objective; re-shuffle tomorrow if the objective changes.
5×6 or 6×5 grid (direct instruction)
Six groups of five (collaborative tasks, jigsaw)
U-shape with inner rows (Socratic seminar)
15 pairs (testing day, integrity-focused)
Separation that survives the first-week chaos
Any 30-student class has at least two pairs you'd rather not seat adjacent (behavior conflicts, testing integrity, IEP accommodations). Paste them into the separation field as comma-separated pairs and re-shuffle — the randomizer satisfies up to 50 attempts before falling back to best-effort placement. For testing days, add aisle-separation as a sanity check and the generator produces a chart with no two conflict-pair students within four seats of each other.
Keep-together for accommodations and peer supports
Pair up your ELL students with bilingual peers. Seat peer tutors next to their tutees. Keep your SEL-support pair adjacent through unit transitions. The generator's keep-together constraint applies across every layout, so re-seating for a different instructional mode doesn't break the supports you've built.
Printing and sharing
The 5×6 chart fits on a single landscape page at 16pt — readable from the teacher's desk. For PLCs and IEP meetings, export a screenshot or print two charts per page to compare before/after rearrangements. Everything stays in the browser; nothing uploads, nothing saves to any account.

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.”
