The Calingaert Score is a weighted average of course grades, where the weights are chosen so that a score of 0 reflects an average letter grade between a P+ and an H-. The weights for the letter grades are as follows:

Grade	H+	H	H-	P+	P	P-	L+	L	L-
Weight	+5	+3	+1	-1	-3	- 5	-7	-9	-11

For example, the Calingaert Score for three courses with letter grades P+, H-, and H would be (-1 + 1 + 3)/3 = +1.0 (assuming the three courses carry the same number of credit hours). The name recognizes Dr. Peter Calingaert, professor emeritus, who devised the measure when he was Director of Graduate Studies.
