Scoring the Computational Fluency CBM ~ RtI for Math Made Easy

There are different ways in which you can score the tests.

You can score the tests based on the number of digits correct. For example when scoring the following problem: 13 + 18 = 31, the answer contains 2-digits and both digits are correct. The student earns 2 points. If the student answered 21, only one digit is correct, so the student earns 1 point.

You can also score students based on the percentage correct.

Another way, which I find easier and just as reliable, is to score students on the number of problems they get correct.

After students have taken the CBM, I grade them by using the last scoring method.  They are graded according to the problems they get correct.  If the problem was solved correctly, I place a checkmark in the box.  After all problems have been assessed, I add up all the checkmarks and place that number on the top.  This score is what I plot on their progress graph, and they also plot on their own graph.
