Level of Education codes for Student profile

I have had a couple of partners (most recently TenarisUniversity) ask for the meaning of the level of education codes in the student profile. I found the following in the research guide and thought it might be useful to include this in the main documentation as it is not intuitive what the codes mean in the download:
