Question about references - my mentor is also my program's DCT. He tells me that he plans to put his letter of reference for me *within* the DCT's verification of readiness section of the application (i.e., rather than just ticking the required box saying I am eligible [which is my understanding of what this section usually consists of?], he will include a full-blown multi-paragraph letter in that space). This (he says) will then allow me to include three *additional* letters of reference from practicum supervisors (since his letter will not technically be taking up one of these spots). He seems pretty sure that this is the way to do it, but it sounds really strange to me that I would get a "free" letter of reference just because my mentor happens to be DCT. Moreover, it seems to me that this might annoy the many sites that have a 3-letter limit, since this seems to be a loopholey way of slipping in 4 letters. Or on the other hand, perhaps sites will miss my mentor's letter entirely, since the DCT verification is more often just boilerplate "yes this student is ready for internship," and perhaps reviewers don't typically look at that section.
Assuming my description of the issue is even coherent - any thoughts?
