I have edited all manner of undergraduate writing in the following subjects:
I have also edited/proofread graduate-level writing for:
Masters theses in Leadership (a.k.a. Organizational Leadership Project(s), or OLPs)
Masters theses in Social Work
Masters theses in Business (MBA Organizational Consulting Project(s) or OCPs)
PhD dissertations (in both Arts and Science faculties)
These projects included elements of structural editing (making sure that the ideas presented flowed logically), stylistic editing (making sure that the ideas are clearly presented and flow logically, and that the language is suitable for the intended audience), copy editing (making sure that the grammar, punctuation, spelling and usage is correct), and proofreading (checking for adherence to design and for minor, mechanical errors in copy such as spelling mistakes or small deviations from style sheet), as well as making sure that the students' bibliographic citations were correct an accurate and matched those in their their references/bibliography.
