John Oliver does a great summary of all the key points (with irony):
Standardized testing CAN be a useful tool as part of a broad educational program but the “reforms” over the past decade+ are NOT RIGOR but a RACKET!
It’s a part of a general corporate takeover of the education system, turning it into a multi-tiered prison system in which our children get abused into submission, parents and kids get turned into obedient debt-slaves, and corporatist masters get rich.
