If the tests scores upon which all of this is based are not valid and reliable then what? We can do all of the statistical analysis and create complex formulas that appear to produce unbiased results. My concern is with the numbers with which we begin, notoriously unreliable test scores.

Calculate how much value we subtract from the human condition when we reduce learning to single metrics of limited validity.
