Catholic Schools in Greater Tucson
Parish elementary schools of the Diocese of Tucson, from St. John the Evangelist on Ajo Way to St. Elizabeth Ann Seton near Shannon Road, plus the Catholic high schools: Salpointe, St. Augustine, San Miguel and Immaculate Heart.
Funding note: Catholic families in Pima County usually weigh the ESA against need-based scholarships from Arizona's Catholic Tuition Support Organization (CTSO), the Tucson diocese's own STO. One or the other for a given child each year, not both.
Arizona's Catholic Tuition Support Organization is the Diocese of Tucson's STO. Because its school list wasn't available for our match, the STO columns below undercount Catholic aid; expect most of these schools to work with CTSO.
Parish K-8s here often price below the ESA range, while the four high schools usually price above it, which is why the ESA-or-STO choice can differ between siblings.
Where they are: Catalina Foothills & the East Side (4), Central Tucson, the University & the West Side (4), South Side, Sahuarita, Green Valley & Vail (4), Northwest Tucson, Oro Valley & Marana (3).
