About the School

Thornton High School fosters a diverse, multi-cultural environment committed to success for all students in preparation for the global workforce and economy.

Students are encouraged to be independent, globally-minded, creative problem-solvers through the International Baccalaureate Programme. The world-renown IB programme “develops inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect.” Students graduating with an IB Diploma have the opportunity to earn up to 24 college credits.

Established in the early 1990s, Thornton’s IB programme is one of the oldest in the state. Thornton implemented the IB programme schoolwide with the 2015 freshman class.

In addition to the IB programme, Thornton offers students challenging Advanced Placement courses and a variety of athletic and extracurricular activities.

Enrollment Information


No matter what your child's passions are or what unique learning opportunity they're looking for, there's a home for them in Adams 12 Five Star Schools. If you are starting your journey with us or transitioning from a different school, you are invited to discover all that our district has to offer to elevate your child's education. Make sure you understand your enrollment options and then find the best fit for your child.

Step 1: Understanding Your Enrollment Options

New to the district and need to enroll now?

In-district families who wish to attend their neighborhood boundary school can use our boundary locator to determine which school their student will attend.

Looking for a school outside your designated attendance boundary?

In-district families who wish to attend a school other than their boundary school and out-of-district families who wish to attend a Five Star District school can apply for admissions via the Choice Program during the specified timelines. Choice is closed for the 2019-2020 school year.  We are currently accepting applications for the 2020-2021 school year.

Please Note: In extenuating circumstances in-district students can request a change of school assignment through the family-initiated school transfer process.

Joining Adams 12 Five Star Schools from out of district?

Out-of-district families who wish to attend a school in the Five Star District can apply for admissions via the Choice program as family-initiated transfers are only available to in-district families. 

Step 2: Gather the Required Documentation

Gather the required documentation

Documentation needed includes: 

  • Parent/Guardian Photo ID
  • Child’s Birth Certificate
  • One Proof of Residence
  • Immunization Records

Step 3: Complete the Online Enrollment Application

The application will ask you to enter information about your family and upload the required documents.  Failure to upload the documents when the application is submitted will delay the enrollment process.
