I don’t understand what you’re getting at. Texas does well on nationally standardized tests. Whose to say their graduation standards are too high, rather than other states’ being too lax?
No, your point was that Texas “is not a paragon of educational achievement.” Please explain how your citation of graduation rates supports that conclusion when you’re not disputing that Texas does better than most other states in test scores.
“Texas is in the lowest decile in terms of high school graduation rates and the lower half of post-secondary educational attainment. It is not a paragon of educational achievement.”
You’re saying “educational achievement” is measured by graduation rates, not test scores.
