1 Refers to one or more parent or other household adult.

2 Total includes other racial/ethnic groups not shown separately in the table.

NOTE: Data based on responses of the parent most knowledgeable about the student's education. Analysis excludes homeschooled students. Reporting standards for Native Hawaiian/Pacific Islander students and American Indian/Alaska Native students were not met; therefore, data for these groups are not shown in the table. Detail may not sum to totals because of rounding. Race categories exclude persons of Hispanic ethnicity.
