Another adult education issue: affordable housing.
“We need to have an apartment without paying a lot of money,” she said. An Alexandria grocery store cashier, Tebeje said she can’t save for school because her rent is so high. “If I get one of these [apartments], I can go to school, too, but now I don’t have time because I work two jobs.” (my emphasis)
In Arlington County, Virginia, which borders Washington D.C., more than 3,600 people have applied for the chance to rent one of 122 new affordable apartments still under construction.
All the work that goes into improving adult education curriculum, standards, professional quality, etc. is kind of a waste of time if no one can afford to attend.

Literacy & Policy 
Great point. I work with adult learners with low incomes in Atlanta, and the number of barriers they face can be astounding. As adult educators and advocates we have to take a holistic approach to improving adult education – meaning we need to look at the entire community (housing, medical issues, etc.). So many factors go into whether our students can make it to class (and be successful in class), and we have to acknowledge them.
