In order for teachers to be considered Highly Qualified as determined by The No Child Left Behind Act (NCLB), they must be teaching in the core subject area of their certification. To meet these standards, a teacher of core academic content must possess:
A Bachelor’s degree
A teaching or intern credential, and
Demonstrated core academic subject matter competence
The core academic content areas include:
Multiple/General subjects
English
Reading/Language Arts
Mathematics
Science
Foreign Languages
Civics/Government
Economics
History
Geography
Arts
NCLB does not require current teachers to return to school or get a degree in every subject they teach to demonstrate that they are highly qualified. NCLB allows these employees to provide an alternate method of evaluation called High, Objective, Uniform State Standard of Evaluation (HOUSSE). This evaluation allows experienced teachers to demonstrate subject-matter competency that recognizes, among other things, the experience, expertise, and professional training garnered over time in the profession.
