Criteria for what counts as good writing

After emailing a forensic science professor, I found the criteria of writing that he believed most professors in the field look for. One point he made was the utilization of primary, not secondary, scholarly sources is very important. He also noted that integrating classic theoretical perspectives with more contemporary research is a key factor (as well as creating "new" solutions to the more contemporary problems). More criteria, which all professors would require, is critical thinking, no gramatical errors, and pertaining to the social sciences -- accurate APA formatting. The professor also mentioned that these expectations increase from course to course as a student proceeds through the transitions from rfeshman to senior and/or undergraduate to graduate.
