Substitute Teaching Matters
1 Full Year
of a student’s K-12 time
is taught by subs
1 in 10
Substantial helps improve the substitute teaching experience for everyone:
students, subs, district staff, teachers, principals and parents.
Students spend up to one whole year of their K-12 education with subs, but educators say it often feels like lost time. We believe students deserve more than a warm body with a worksheet.
Every student deserves someone substantial: a caring, energetic and well-trained sub who can make the most of class time.
Districts partner with us to help break out of patterns and improve how they recruit, train and support subs. We’ve been called consultants, process improvement geeks, and fearless optimists.
As long as we’re helping districts tackle what they thought was impossible and improve the substitute teaching experience, we’ll gladly wear any of those labels. Learn more.
