A Private School Opens on Sweetgum Road This Month. High School Comes in 2027.
By The Magnolia Standard · August 18, 2026
Magnolia gains a second private option this month, and this one intends to grow into a full twelve-grade school.
Discovery School of Innovation opens a new campus in Magnolia this month at 28277 Sweetgum Road. The site runs about six acres. It is built for pre-K4 through eighth grade, and the school says the buildings include classrooms with natural light, separate space for arts and sciences, outdoor learning areas, and athletic facilities.
The school is private. That is the first thing families will want to be clear on, because it is the thing that decides whether the rest of this applies to you. Discovery is not part of Magnolia ISD, it does not draw from a zoned attendance boundary, and it charges tuition. The school has not published a tuition figure, so anyone weighing it will have to ask directly.
The Magnolia campus is an expansion. Discovery already runs a school in the Woodlands area, and this is a second location rather than a relocation. Enrollment for the 2026 to 2027 year is open, and the school has described availability as limited.
The longer plan is the more interesting part. Discovery intends to start a high school program in the fall of 2027, opening with a ninth-grade class in August of that year and adding one grade each year until it reaches twelfth. If that holds, a family enrolling a fourth grader this month could keep that child in the same school through graduation without another move.
Founder and director Catherine Sagar called the expansion "an exciting new chapter" for the school, and described the aim as building "a school where every child is known, challenged and inspired."
Two thoughts worth holding onto. Plans to add grades year by year are exactly that, plans, and they depend on enough families signing up to fill each new one. A ninth grade announced in 2026 for 2027 is a real intention, not a guarantee. Ask what happens if a grade does not fill.
The other is what this says about the west side of the county generally. Growth here has mostly shown up as rooftops and retail. A private school putting six acres behind a twelve-year plan is a different kind of bet, and a slower one.
Families who want to see it can arrange a tour through the school.
