We have been looking at two different numbers that have been used to describe the availability of physics in U.S. high schools: 60% and 95%. Last month we noted that the U.S. Department of Education Office of Civil Rights (OCR) includes over 7,000 more public schools in the denominator than American Institute of Physics (AIP) Statistics does. Almost 4,000 of the additional schools are special education, alternative, or other schools that do have seniors enrolled. An additional ~3,350 are schools that have a grade 9, 10, 11, or 12, but no seniors enrolled. The 95% number reported by AIP Statistics is the proportion of "seniors" attending a school where physics is offered "regularly." The italicized words explain the bulk of the difference between the 60% and 95%.
