Does CMU accept ACT scores after the ED deadline?

I’m not sure if my ACT scores will be sent in time due to September ACT writing scores being delayed.

can you find an email address or phone number for CMU admissions to ask them?

Call the admissions office and ask. They have probably fielded this question a hundred times already.

It’s appeared on this site hundreds of times already. Do you think it’s in CMU’s best interest to be harsh and strict about this? They ARE DYING TO ADMIT YOU… don’t forget that. If you scan this very page – half the questions are about this very issue.

Assuming ACT ceases acting like the total incompetent it has been lately and gets the grading finished in the next couple weeks, you will be fine since the test can arrive after Nov 1 and CMU even takes the Nov SAT test for ED for which scores will not be released until later in Nov, see https://admission.enrollment.cmu.edu/pages/early-decision-plan
