1. High resource parents have been doing this for decades for their mathematically gifted children. I went to geek camp in high school where middle and high school students were breezing through college level math. It's absurd to hold children back when they're capable of this. https://twitter.com/conor64/status/1386843508351258624

2. The reasons given in the past (and currently) were that it was necessary for students to stay in math classes with their same-age peers even if they were bored out of their mind and should have been studying harder math.

3. High resource parents who aren't who are unable to teach their children higher level math on their own hire private tutors, send their children to geek camps, enroll them in college classes, and more.

4. Here's a list of Math Programs for Kids in Massachusetts from January 2019: https://www.bostontechmom.com/math-programs-for-kids-in-massachusetts/

5. American students are -already- far behind students in other countries when it comes to math.

"Most troubling to researchers is that 30 countries scored higher than U.S. students in math..." https://www.usnews.com/news/education-news/articles/2019-12-03/us-students-show-no-improvement-in-math-reading-science-on-international-exam

6. This infographic is sorted by reading scores, on which we're also behind.

8. 2018 is the most current year for which results are available. The PISA, developed by the OECD (Organisation for Economic Co-operation and Development) is "administered every three years that measures what 15-year-old students have learned in math, reading and science."

10. Test scores are not everything but as a former gifted kid I can’t support any education reform that’s based on the misguided idea that having a better learning experience for some students has to be done at the expense of students capable of doing more.
