Any help is appreciated.

Answer 1

You should look into dbo.IM_EN_Main_Qualifcation_with_title_vw. Your problem is that you are doing something like
c1 + c2
where c1 and c2 are columns, c1 is of type smallint, c2 is textual and when the view was created, c2 contained only numeric values, but recently a textual data was added, which contains '20PA'. You need to change the view to convert c1 to textual data, using CAST or CONVERT.
EDIT
As Aruna Raghuna pointed out, it turned out to be an issue in the College_Year column, which in at least a case, instead of the expected numeric value contained text as well. While I have shown the op the way to find the answer, frankly, it was Aruna, who searched for the issue. Thought process being used was as follows:
check column types and find out which are of smallint types, so that we will know where to look for the problem
check textual columns and find out which of those contained the text found in the error message
possible final step is to fix either the query or the functionality along with the data, so this kind of issue will not be recurring in the future
