2. 93% of studies have found student testing, including the use of large-scale and high-stakes standardized tests, to have a "positive effect" on student achievement, according to a peer-reviewed, 100-year analysis of testing research completed in 2011 by testing scholar Richard P. Phelps.

That's another advantage of non-parametric tests. The main disadvantages are 1) Lack of statistical power if the assumptions of a roughly equivalent parametric test are valid, 2) Unfamiliarity and 3) Computing time (many non-parametric methods are computer intensive). How much of a problem each of these are varies.

Tests that measure performance against a fixed set of standards or criteria are called criterion-referenced tests. ... It should be noted that norm-referenced tests cannot measure the learning achievement or progress of an entire group of students, but only the relative performance of individuals within a group.
