Q: What does the status "evaluating reviews" indicate?

The status "evaluating review" indicates that the review reports have come in and the editor or members of the editorial board are going through the review to come to a decision on your manuscript. If the editor is satisfied with the reviews, he or she will take a decision. If however, the editor feels that one or more of the reviews are weak or if the reviewers have conflicting opinions, he or she might send the manuscript for an additional review. The next status change will give you a clearer idea.
