ThinkWave

ThinkWave is a cloud-based school administration system with teacher gradebooks and a separate free online gradebook. It is most compelling for education programs that want grades, attendance, student records, portals, and communications in one place. Its strongest trade-off is breadth against a 15-student limit on the free school plan and separate, per-teacher pricing for paid gradebooks.

Overview

ThinkWave combines student administration, attendance, grades, gradebooks, and student and parent portals. Teachers can share assignments and handouts, collect student work online, and send messages or announcements by class, group, or school. This scope can suit a school coordinating records and communication across its community; a program seeking only a simple gradebook may not need the broader system.

ThinkWave says it serves K–12 schools, colleges, trade schools, homeschool networks, international schools, and training programs. Founded in 1997 and headquartered in Sebastopol, California, it spans a wider range of education settings than K–12 alone.

Key features

Teachers can use points, letter, pass-fail, or custom grading scales, weight assignment types, and calculate term averages. Customizable report cards and transcripts draw on grades, comments, attendance, and custom student data, making the system useful where classroom marks need to feed into formal student records.

Online assignment collection and handout sharing extend the gradebook into classroom workflow. Files can be up to 25 MB each, and the school system includes 100 GB of storage. Those allowances support substantial document sharing, though the individual file cap matters for larger materials.

Messages and announcements can reach students and parents by class, group, or school, including through group email. Student, attendance, grade, and custom-field data can be exported as CSV, a practical option for moving records into other workflows. ThinkWave says it uses password-protected accounts, SSL encryption for data transmission, and Google Cloud data centers for stored data; it also says it does not sell student or other user data.

Pricing

ThinkWave uses a freemium model, with a free 30-day trial of the school administration software that includes all features. The free school plan is capped at 15 students, so it is a constrained starting point for a school rather than an unrestricted long-term option. The pricing note gives paid school-system pricing from $17/mo; schools that need the system beyond the trial should weigh that ongoing cost against their enrollment and workflow needs.

The separate Free Solo Gradebook costs nothing and does not expire. It has no stated limits on students, classes, or assignments, with uploads up to 25 MB per file. That makes it the clearest fit for an individual teacher wanting a lasting gradebook without paying, but it is not the same as the full school administration system.

Premium Gradebook plans are billed per teacher per year and include 100 GB online storage, ad-free use, and uploads up to 25 MB per file. The rate falls with larger teacher groups: 1 teacher costs $49.95 a year; 2–9 teachers, $39.95 a year; 10–19, $38.95 a year; 20–50, $37.95 a year; 51–75, $36.95 a year; 76–100, $35.95 a year; 101–125, $34.95 a year; 126–150, $33.95 a year; and 151–175, $32.95 a year. The lower group rates favor schools buying for larger faculties, while a single teacher pays the highest listed per-teacher rate. These are gradebook plans, distinct from the school administration system.

Platforms

ThinkWave supports Android, iOS, Linux, macOS, web, and Windows, giving schools and teachers options across mobile and desktop environments.

Who it's for

ThinkWave is a strong candidate for schools and education programs that need student administration, attendance, customizable reporting, gradebooks, and family communication together. Its free Solo Gradebook also suits teachers who want an ongoing standalone option. Schools with enrollment above 15 should not treat the free school plan as a complete long-term solution, and programs that only need basic grading may find the full system broader than necessary.

Pros and cons

• Pros: Student records, attendance, grading, portals, assignments, and communication sit within one school system, reducing the need to split those workflows across separate tools.
• Pros: The free gradebook does not expire and has no stated student, class, or assignment caps, making it a substantial starting option for an individual teacher.
• Pros: Multiple grading scales, weighted assignment types, and customizable reports support varied grading practices and formal recordkeeping.
• Cons: The school system's free plan is limited to 15 students, which restricts its usefulness for many schools.
• Cons: Premium Gradebook pricing is per teacher per year; the lower rates apply only to larger teacher groups, so a single teacher faces a higher annual rate.
• Cons: Uploads are capped at 25 MB per file, and third-party integrations are not named, which may constrain large-file sharing or integration planning.

Verdict

Choose ThinkWave when your school or education program needs student administration, gradebooks, attendance, portals, reporting, and communication in a single system, and when the paid school plan fits your enrollment. The non-expiring free gradebook is a meaningful entry point for individual teachers. Look elsewhere if the 15-student free school cap is too restrictive or if you need only a lightweight gradebook rather than a wider administration system.
