Disclaimer

The tools and guides on Teachers Tool are for general educational use. Last updated June 17, 2026.

Check important results

Our calculators follow standard methods, but settings differ between schools. Grade scales, GPA weighting and curve rules vary. Always confirm a result against your own school's policy before you record or report it.

Not professional advice

The guides share practical teaching ideas. They are not formal training or policy advice. Follow your school's rules and your professional judgement first.

Accuracy

We aim for correct, useful tools, but we cannot guarantee every result fits every situation. Use the output as a strong starting point, not a final authority.

If you spot an error in a tool, please tell us through the contact page so we can fix it.
