Hi,
I’m a senior in high school and I was wondering if anyone knew what the new SAT score requirement would be for the School of Art at Carnegie Mellon University?
What do you mean by “score requirement”? If you are referring to the rSAT then it will be impossible to know until the end of the admissions cycle what the range will be. Therefore, you are best off converting CMU’s standardized test statistics to the new test via the College Board concordance tables or Score Converter. See the link below for the most recent set of stats.

School of Art will undoubtedly also require a portfolio submission but not a subject test. 
Good luck!
