The state should offer a license with minimal requirements that allows content experts to teach part time.
Iowa does not offer a license with minimal requirements that
would allow content experts to teach part time.

Offer a license that allows content experts to serve as part-time
Iowa should permit individuals with deep subject-area knowledge to teach a limited number of courses without fulfilling a complete set of certification requirements. The state should verify content knowledge through a rigorous test and conduct background checks as appropriate, while waiving all other licensure requirements. Such a license would increase districts' flexibility to staff certain subjects, including many STEM areas, that are frequently hard to staff or may not have high enough enrollment to necessitate a full-time position.
Iowa recognized the factual accuracy of this analysis.
Part-time licenses can help alleviate severe shortages, especially in STEM subjects.
Some of the subject areas in which states face the greatest teacher shortages are also areas that require the deepest subject-matter expertise. Staffing shortages are further exacerbated because schools or districts may not have high enough enrollments to necessitate full-time positions. Part-time licenses can be a creative mechanism to get content experts to teach a limited number of courses. Of course, a fully licensed teacher is best, but when that isn't an option, a part-time license allows students to benefit from content experts—individuals who are not interested in a full-time teaching position and are thus unlikely to pursue traditional or alternative certification. States should limit licensure requirements to those that verify subject-matter knowledge and address public safety, such as background checks.
Part-Time Teaching Licenses: Supporting Research
The origin of this goal is the effort to find creative solutions to the STEM crisis. While teaching waivers are not typically used this way, teaching waivers could be used to allow competent professionals from outside of education to be hired as part-time instructors to teach courses such as Advanced Placement chemistry or calculus as long as the instructor demonstrates content knowledge on a rigorous test. See NCTQ, "Tackling the STEM Crisis: Five steps your state can take to improve the quality and quantity of its K-12 math and science teachers", at: http://www.nctq.org/p/docs/nctq_nmsi_stem_initiative.pdf.
