GRADING CALCULATORO N L I N EA little clarity for every grade.

A printable grading table for marking

Short answer: enter the total points on the test, set your grade boundaries, and print. You get one row per possible score, so you divide nothing per student.

Marking thirty papers with a calculator means thirty divisions, each one a chance to mistype. A table on the desk means thirty lookups. Lookups do not slip.

Three steps

  1. Open 04 — Teacher table on the calculator.
  2. Enter the total points on the test. A 25-point test gives 26 rows — full marks down to zero, because zero is a score a student can get.
  3. Open Customize the grading scale and enter your boundaries. Then press Print grading table.

What the sheet looks like

On the default A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60 scale, a 25-point test begins and ends like this:

Points earnedPoints missedPercentageGrade
250100.00%A
23292.00%A
22388.00%B
20580.00%B
17868.00%D
151060.00%D
141156.00%F
0250.00%F

The points missed column is the one you will actually use. You count the marks you took off, not the marks you gave — so you read the table from the column that matches how you mark.

On a 25-point test each point is worth exactly 4 percentage points, which is why the letters change in clean blocks. On a 30-point test each point is 3.33 percentage points and the blocks are uneven. The table absorbs that for you; mental arithmetic does not.

Your scale, including pass/fail

The default scale is ours, not a standard. Real policies differ: SUNY Broome's policy AA4010 puts A at 93–100, while the Lincoln Memorial University PA program catalog puts A at 90.00–100%. Enter the boundaries your department actually uses.

The rules for the scale: 2 to 12 rows, unique labels of 1 to 12 characters, thresholds ordered highest to lowest, and the last row must start at 0.

That is enough for most real scales:

Your scale is printed on the sheet, under the heading. So the sheet says what it assumed — useful six weeks later, and useful if a student asks.

What prints

Only the table. The input panels are hidden in print, and the footer carries the site name and a reminder to check your school's grading rules.

Set your browser to print background colours if you want the table to look like the screen; plain is fine and uses less ink.

Limits, and what to do about them

1 to 500 points, whole numbers only. A fractional total such as 20.5 is refused: "Use a whole number of points for the table."

That is a real limit, not an oversight. The table steps one whole point at a time. If you award half marks, a table in half-point steps would be a different table with twice the rows.

The workaround is to count in half-points. A test worth 20 points with half marks available is a 40-half-point test. Enter 40 as the total, and read each row as half-points: row 35 is 35 half-points, which is 17.5 out of 20 — 87.50%. The percentages and letters are correct either way, because the ratio is the same.

Above 500 points, or for a single student's score, use 01 — Test score instead. From points to a percentage to a letter covers that mode, including half marks and the boundary rule.

One thing to know before you print

Letters in the table come from the unrounded percentage, and the percentage column is displayed to two decimals. On most totals they agree. But if your department rounds to the nearest whole percent before assigning a letter, a score sitting just under a boundary will differ from this sheet.

Check your department's rule once, then trust the sheet. How this calculator works states our rounding rule in full, so you can tell exactly where the two would disagree.

Next

The table is a calculation, not an official grade record. Your school's rules decide the grades you enter.
