Among the barriers that Reuters documented:
* Applications that are made available just a few hours a year.
* Lengthy application forms, often printed only in English, that require student and parent essays, report cards, test scores, disciplinary records, teacher recommendations and medical records.
* Demands that students present Social Security cards and birth certificates for their applications to be considered, even though such documents cannot be required under federal law.
* Mandatory family interviews.
* Assessment exams.
* Academic prerequisites.
* Requirements that applicants document any disabilities or special needs. The U.S. Department of Education considers this practice illegal on the college level but has not addressed the issue for K-12 schools.
