  In 2018, in response to the proposed elimination of physics at a
predominately Hispanic and socioeconomically disadvantaged (SED) high school,
the Northern California/Nevada chapter of the AAPT investigated school
demographics and their effect on physics offerings in public high schools in
our region. As access was a key issue, the focus was on public, non-charter
high schools, which are free to students and do not require winning a lottery
for attendance. As reported previously, the data revealed that the percentage
of Hispanic students and the percentage of SED students at a high school are
highly correlated (r^2=0.60). Additionally, these factors could be used as
predictors of a school's physics offerings. To determine if the disparities in
course offerings extended through other Advanced Placement (AP) STEM classes
the data was further analyzed, revealing that as the popularity of an AP exam
drops, so do the relative odds of it being offered, when comparing schools with
different demographics. A Northern California public high school student is
much more likely to get a strong selection of AP STEM classes if their school
serves an affluent, non-Hispanic student majority rather than mostly poor,
Hispanic students.
