My son took it and it seems like everyone else from his testing center got their scores last month but his status still shows as “Registered.” The ACT site says scores can be released up until January, but I don’t know if this delay means anything.
I got mine the date they are first released. Did your son take it with writing? If not, then it is possible that they either messed something up or perhaps some of the information was filled out incorrectly and needs correcting.
