"The curve" is the permitted range of each letter grade that can be awarded, for example, 0–3% A+, 3–7% A, etc. Curves vary between different law schools, as do the rules for when the curve is mandatory versus suggestive. It is common for the curve to be mandatory for first-year ("1L") courses, and for classes above a certain size.
The ECTS grade is not meant to replace the local grades but to be used optionally and additionally to effectively "translate" and "transcript" a grade from one institution to another. The ECTS grade is indicated alongside the mark awarded by the host institution on the student's transcript of records. The receiving institutions then convert the ...
To ensure that this does not happen, teachers usually put forth effort to ensure that the test itself is hard enough when they intend to use a grading curve, such that they would expect the average student to get a lower raw score than the score intended to be used at the average in the curve, thus ensuring that all students benefit from the curve.
Below is the grading system found to be most commonly used in United States public high schools, according to the 2009 High School Transcript Study. [2] This is the most used grading system; however, there are some schools that use an edited version of the college system, which means 89.5 or above becomes an A average, 79.5 becomes a B, and so on.
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.

In educational statistics, a normal curve equivalent (NCE), developed for the United States Department of Education by the RMC Research Corporation, [1] is a way of normalizing scores received on a test into a 0-100 scale similar to a percentile rank, but preserving the valuable equal-interval properties of a z-score. It is defined as:
