Well, not really. I was involved in education as a teacher/campus administrator/central office administrator for 36 years, 31 of them in Texas. If you go online and look at the Texas curriculum and requirements for graduation, it looks pretty stringent. You have to pass five End of Course exams in Texas to graduate. However, for example, to pass the Algebra I EOC exam, you only need to get 37% of the problems correct, and you have multiple opportunities to do that. Most of the problems are multiple choice, so someone guessing wildly will get around a 25%. Plus, "graduation committees" can circumvent most of the requirements. Theoretically, you can only have a maximum of 10 absences a year to be able to earn credit in a course. What a joke. I have seen these committees approve a student with 60+ absences for graduation. And I could go on and on. The point is that a high school diploma from a lot of schools means very little. In many instances, SAT and ACT scores are the only level ground that colleges have to judge the quality of education a student receives.
