Learning Styles and Reading Comprehension

At my school we are working on Tier 1, 2 and 3 learning which essentially asks the teacher to differentiate learning with your students who are not meeting all of your objectives.

Two main items that we are looking at are learning styles and reading comprehension. Sure we think we know our students after a year of being with them, but isn't most of it anecdotal.  Next year I am going to talk to my department about having our students complete this learning style test (no login/password required).  

Secondly I want our teachers to consider reading comprehension using this test (or similar ones later).  Of course the hard part is once we know how learning style and reading comprehension the hard part is taking the information and putting it into action (more on that later).
