Sierra School at Main Street

Sierra School at Main Street is a partnership with St. Vrain Valley School District. Sierra School serves students from kindergarten through age 21 in its Broad-Based Educational Services & Therapies (B.E.S.T.) Model classrooms and 1st grade through 6th grade in the Academic Rotational Model classroom. At Sierra School, we take an individualized approach to educating students with specific eligibilities, which starts with building strong foundational skills in the areas of language, visual performance, fine motor skills and gross motor skills.

Our Students

Students are referred by St. Vrain School District to attend Sierra School and are generally in grades K–12 (aged 5 to 21). They face disabilities in a variety of areas, including autism, serious emotional disability, specific learning disability, multiple disabilities, intellectual disabilities, other health impairments, and traumatic brain injury

Our Staff

We are proud to employee special education teachers and a school social worker, all of which are licensed through the Colorado Department of Education. We also have a Board Certified Behavior Analyst (BCBA) and a team of ABA trained assistant teachers. St. Vrain School District provides related services such as Speech and Language, Occupational Therapy, and Physical Therapy. All Sierra School staff are trained in Handle With Care for crisis intervention.

By focusing on key areas — academics, behavior modifications, support services, and transition / life planning services — we are able to meet the individual needs of all students through these varied approaches to instruction. Through collaboration with a student’s IEP team, we are able to choose the most appropriate learning model based on a given student’s present levels of performance, social capabilities, motor coordination, and ability to learn in a group setting.

Utilizing four specific instructional rotations, students are assessed academically, gain self-regulation skills, learn with district-aligned academic curriculums, and utilize integrated technology.

Serving students with significant autism and developmental disabilities, our model takes learned skills and practically applies them to the multiple environments in which a student would use those skills. Students spends portions of their day rotating through different modalities of instruction, the length and the frequency of each rotation is individuality designed for each learner and based on their current skills and future goals.

Each student enrolled in the model has individualized behavior programming which is driven by Functional Behavioral Assessments (FBA). We aim to identify the behaviors that continue to disrupt our student’s ability to access their environment and learning. We then use the data collected from the FBA and classroom data to device strategies that get to the root function of the students disrupted behaviors.

Sierra School works closely with the Envision and Imagine, the local Community Centered Boards (CCBs) to ensure that students have ample opportunities to explore potential post-secondary education and career opportunities. The high school BEST Model students access life skills and transition programming based on the Assessment of Functional Living Skills and other transition curricula.

We partner closely with St. Vrain School District to ensure that students are connected with all available district and community opportunities such as sports teams at the students’ home schools, the School to Work Alliance Program (SWAP), and the local Community Centered Boards (CCBs) and mental health providers. Additionally, Sierra School students in our high school Language Model class participate in weekly community outings.
