For teachers

Grading tools that give you the period back

Marking is skilled work; the arithmetic around it is not. These tools handle the repetitive calculations of a teaching week: converting wrong answers into grades, building a printable chart for a new test size, grading a whole class set from one list, and applying a curve you can explain to students, parents and your department head.

Start with the tool most teachers keep open all year, the EZ Grader, which reproduces the classic sliding grading wheel for any number of questions. When a paper test uses unequal points, the Test Grade Calculator reads points instead. The Class Grade Calculator grades an entire set at once from a list of wrong-answer counts pasted in mark-book order, and the Grading Chart page prints clean charts for common test sizes. When an assessment proves harder than intended, the Grade Curve Calculator applies the square-root, flat points and percentage-boost methods transparently, so the adjustment is a policy rather than a favour.

Every teacher tool on this page works on the US standard and plus/minus scales and, where relevant, the Canadian and Australian scales used by our international readers. Nothing you type into a calculator is transmitted or stored; the computation happens in the browser tab in front of you, which means student scores never leave your device.

A note on accuracy

These calculators apply published grading scales mechanically and consistently, which removes arithmetic slips but not judgement calls: rounding at a grade boundary, partial credit and borderline reviews remain yours, and your school's grading policy always overrides a generic scale. Each tool page prints the formula it uses and a worked example, so a result can be checked by hand in seconds when a student or parent asks how a grade was reached.
