Delivering Well Prepared Teachers Policy
The state should ensure that secondary science teachers know all the subject matter they are licensed to teach.
Utah does not offer a general science certification for secondary science teachers. However, the state does offer a physical science endorsement. Candidates are required to pass the Praxis II Physical Science test.
Praxis Test Requirement www.ets.org
Require secondary science teachers to pass a content test for each discipline they are licensed to teach.
States that allow combination licenses across multiple science disciplines—and require only a comprehensive content test—are not ensuring that these secondary teachers possess adequate subject-specific content knowledge. Utah's required assessment combines both physics and chemistry and does not report separate scores for each subject. Therefore, a candidate could answer many physics questions, for example, incorrectly on the combination content test yet still be licensed to teach physics to high school students.
Utah recognized the factual accuracy of this analysis. The state added that the physical science endorsement referenced in the analysis does qualify a teacher to provide instruction in basic chemistry and physics courses as described in the report. However, teachers with this endorsement may not provide instruction in either the advanced placement or concurrent enrollment versions of either chemistry or physics. This flexibility is intended to aid scheduling in rural areas as well as help to create smaller class sizes in introductory chemistry and physics courses.
Utah also noted that its licensure requirements for science teachers are intended to balance high standards for teachers and flexibility for districts, particularly rural districts, in meeting the hiring needs in an area that is consistently one of the most critical teacher-shortage areas in the state. As in all areas, quality evaluation and employment decisions of the building principal, in addition to state licensure requirements, are vitally important to ensuring that every student has a highly effective teacher.
NCTQ is not advocating against general science teachers and can see why such a certification is particularly advantageous for rural areas. However, secondary-level students need teachers who are well prepared to teach advanced subject matter, and requiring passing scores on a content test for each discipline that teacher candidates are licensed to teach is the only way to ensure adequate subject-matter knowledge.
Specialized science teachers are not interchangeable.
Based on their high school science licensure requirements, many states seem to presume that it is all the same to teach anatomy, electrical currents and Newtonian physics. Most states allow teachers to obtain general science or combination licenses across multiple science disciplines, and, in most cases, these teachers need only pass a general knowledge science exam that does not ensure subject-specific content knowledge. This means that a teacher with a background in biology could be fully certified to teach advanced chemistry or physics having passed only a general science test—and perhaps answering most of the chemistry or physics questions incorrectly.
There is no doubt that districts appreciate the flexibility that these broad field licenses offer, especially given the very real shortage of teachers of many science disciplines. But the all-purpose science teacher not only masks but perpetuates the STEM crisis—and does so at the expense of students. States need either to make sure that general science teachers are indeed prepared to teach any of the subjects covered under that license or allow only single subject science certifications. In either case states need to consider strategies to improve the pipeline of science teachers, including the use of technology, distance learning and alternate routes into STEM fields.
