Will test-optional colleges take my ACT score into consideration if I don’t have the ACT writing portion this year?
The first part of your question asks: can I submit an ACT without the writing portion. This depends on the school. Many require the writing portion, but many do not. You will need to check with the specific schools to which you’re applying.
The second part of your question asks: can I submit an ACT score to a test-optional school. Of course! Test-optional does not mean test-blind. In fact, if you are a student from a reasonably privileged background, you will be expected to submit a strong test score.
