About Us

Our Story

Stellar Virtual was founded in 2019 with one school in Texas and the mission to Empower Families and Unleash Potential. Today, Stellar Virtual has grown to eight schools across the country. Stellar Virtual is committed to providing families with Education with Destination through our full-time, online public schools. We believe in educating the whole child with essential support to succeed socially and academically. 

Our “School of One” approach offers a safe, flexible, and personalized experience to meet every student's unique educational needs. We go beyond traditional school curriculum goals to measure both content and application of learning in authentic ways.

Stellar Virtual’s’ K-12 schools lay the foundation for each extraordinary individual to succeed in college, career, and life with the support of caring and nurturing teachers who deliver high-quality, engaging learning. 

We provide educators with access to and support for non-downloadable software for teaching, administration, enrollment, student progress monitoring, development, customization, and delivery of online courses, lessons, and exams.
