I don’t know why you are assuming when I am right here and you can just ask. Well okay I know why you are assuming I am just going to pretend that I don’t.
It is one standardized test given once a year. Kid is sick during it? No appeal. Kid had a bad teacher that year? No appeal. One single thing goes wrong on a single day of an entire year and your kid lags behind for at least another year. No teacher recommendations, no gpa, no retest, no other options. Maybe next time ask before you assume.
Oh and it isn’t some great equalizer either. I see tutoring places bragging that they can get your kid a better score on the test. If you have the money and the time you can get your kid in the program.
