Ottawa Twp Hsd 140, IL - District Data

Original Research by School Decision on Ottawa Twp Hsd 140

Ottawa Township High School District 140 serves a high school population across LaSalle County towns including Ottawa, Marseilles, Grand Ridge, Oglesby, and Ransom. The district operates two campuses: Ottawa Township High School and a facility at the LaSalle County Detention Center.

The district enrolls roughly thirteen hundred students across grades nine through twelve, distributed fairly evenly among the grade levels. The student body is predominantly white, with a smaller but meaningful share identifying as Hispanic. Smaller representations of Asian, Black, and multiracial students round out the enrollment. Data on free-and-reduced-price lunch eligibility and English learner counts were not available.

State assessment results for science at the elementary and middle grades are not reported, which reflects the district's high school focus; the district does not serve the grade levels Illinois assesses for science proficiency. No proficiency data, graduation rate, or four-year academic trend information was available from state sources.

The district stands out for one lasting curriculum decision: in 2022, the district opted out of teaching Illinois' state-adopted comprehensive sex education curriculum that was introduced statewide under the REACH Act. The new curriculum incorporates the National Sex Education Standards. Because the state law included an opt-out provision, Ottawa Township HSD 140 chose not to implement the updated lessons. This means students receive health instruction aligned with the district's own approach rather than the state's revised standards. Parents evaluating the district's philosophy on health and sexuality education may want to look into this choice further with the district directly.

Chronic absenteeism in the district runs higher than the median among LaSalle County's districts, placing it in the bottom quartile of peer districts on that measure. The district's per-pupil current spending falls in the middle range but toward the lower end compared to other county districts.

Housing in the district's service area spans towns with moderate values. The weighted median home value across the district's zip codes sits in the mid-range for Illinois, with most properties falling in a band that reflects rural and small-city character. The Ottawa zip code, which carries the largest population weight, shows rental listings available. Year-over-year home value appreciation has been modest but positive. The housing market shows steady demand but lower supply, meaning homes typically remain listed for a moderate number of days before sale.

The district operates at a scale typical for a county-seat region: large enough to support a main high school campus but small enough to serve a defined local footprint. Parents considering the district should note that state proficiency and graduation data were not available to assess academic outcomes directly. The chronic absenteeism rate and the curriculum opt-out are the clearest metrics by which to evaluate the district's operational environment and instructional philosophy.
