I-9b: Percentage of Public High School Students in Classes Taught by an Instructor with Certification and a Postsecondary Degree in That Subject, for Selected Subjects, 2011–2012

* The Natural Science category aggregates teachers of general science and specific science disciplines (e.g., chemistry). Such teachers are considered to hold a credential in the subject they teach if the degree or certification is in general science or a specific science discipline.
** The Social Science category includes (and treats as credentialed in social science) history teachers who have a postsecondary degree and/or certification in general social science (including social studies) or a constituent discipline. (The collector of these data treats history as a social science discipline rather than as one within the humanities field.) See the “Note on the Credentials of ‘Social Science’ Teachers in Public High Schools” for further explanation of the relationship between the “history” and “social science” categories.
! Interpret data with caution. The standard error for this estimate is between 30% and 50% of the estimated value.
† The population in this category was too small to achieve a reliable estimate.
