Access To Online Learning

The school partners with Microsoft and Lenovo to provide cutting-edge technology. GOAL offers a blended education for learners wishing to gain greater control over their education. It provides a laptop computer for students to use while enrolled in school. The computer does not cost the student anything, but it is returned at the end of each school year, or when the student graduates. Also, if a student needs help accessing the Internet, GOAL High School provides a T-Mobile hotspot.

Online And In-Person Learning and Extracurriculars

Colorado law allows GOAL High School students access to extracurricular activities at their local high schools. Students can also take one course per semester at their local high school if they desire.

Also, GOAL offers around 40 student drop-in centers statewide. This provides students with one-on-one learning opportunities along with social programming activities, student government, movie nights, and proms. This option for face-to-face support allows students to meet up with teachers and receive feedback on their academic progress.
