I hope this isn't a silly question, but I was wondering how acceptable it'd be to copy and paste a certain structure and some particular sentences in letters of recommendation.
Of course, I'm not thinking of copying and pasting anything very specific about the candidate, but there are certain traits that are shared among students and I also have a certain structure that I like and ties nicely with particular sentences (e.g., when talking about the student as being collegial, responsible, always meeting deadlines etc.). I'm not good with words so the truth is that the more I can reuse the phrases that I like, the faster I can write it and the quality of the text will likely be better as well.
Would this be flagged by some review software? If it is, would one regard it as unethical to reuse stretches of previous letters? I should clarify that all the particular strengths, projects etc. of the student won't be copied and pasted, just sentences about general traits and so forth, or greetings, paragraph transitions, all the repetitive stuff. I guess my real question is: is it ok to use a standard template and just make the required adjustments? Or do I need to keep rephrasing the same points?
