Tip sheet or simple toolkit for tutors that might be working with individuals with undiagnosed learning difficulties

Does anyone have a tip sheet or small toolkit to possibly help adult literacy tutors that might have a student with undiagnosed learning difficulties? Maybe a sheet like "if you see this....try this...."?

Our state association, PAACE, has a lot of members who are volunteer tutors and we are trying to provide more simple resources to help them with the wide range of adult basic literacy learners they tutor. Any suggestions on resources, speakers, or supports we could highlight at one of our monthly statewide networking meetings would be greatly appreciated!
