Considering the prominence attached to written corrective feedback (WCF) within the domain of second/foreign language (L2) acquisition, automated writing evaluation (AWE) tools have steadily gained ground over the last two decades. The current study was an attempt to investigate the extent incorporating an AWE program, known as Criterion®, within a process writing framework would affect learners' writing quality in an English as a foreign language context. Moreover, we drew a comparison between the overall effects of computer‐ versus teacher‐generated WCF. Participants consisted of 53 tertiary level students from two intact essay‐writing classes. The within‐group findings revealed that the experimental group's writing scores rose significantly from the pretest to posttest after receiving automated WCF over several weeks. Significant progress was also noticed on all rounds of scores obtained from five essays assigned to this group except between the first and the second. As for the comparison between computer‐ and teacher‐administered WCF, the former condition was found to be more efficient. Overall, the findings provide a deeper insight into the workings of an automated evaluation tool and how it was employed in the L2 classroom to impart consistency to the assessment procedure and ease the burden traditionally placed upon teachers.
