According to Actstudent.org, most ACT scores are available any time of day once they are loaded into the system. The actual time of day is not regulated or revealed. Depending on testing dates and the quantity of tests, it can take three to eight weeks for results to appear online.
The average time frame for ACT scores is three weeks before they are added online and an additional week for mailed copies. Some students do have to wait longer, especially if they take the ACT Plus Writing tests. Scores for the ACT are processed and inputted into the online database each week, but each Wednesday and Friday are the most common times for new scores to be added.
