Make every flex period
count
Assign the students who need support and let everyone else choose. Teachers can run intervention, enrichment, SEL, or behavior sessions, and administrators get a clear view of who's getting support across your MTSS tiers.

“I tell people every day, I run a city. There's 4,000 people in this building. Flex is how we make sure the kids in your room are accounted for.”

Turn flex time into targeted support for every student
Flex periods build time into the school day for intervention and enrichment. Securly Flex handles it in six steps.
- Set up the period. Pick the days, times, and sign-up cutoff.
- Schedule activities. Teachers add sessions with a room, capacity, and priority.
- Place students who need support. Required sessions outrank student choice.
- Let students choose. They sign up on web or mobile before the cutoff.
- Fill the gaps. Autoassign fills open seats, and Catchall tells anyone left where to report.
- Take attendance. Teachers mark Present, Absent, Late Excused, or Late Unexcused, with QR or barcode check-in. Admins see Full Attendance and the Cut List, and attendance exports to CSV for your SIS.
Rosters are done before first bell
Autoassign fills every open seat, automatically
Before each flex period starts, Autoassign places every unregistered student into an eligible session. It weighs student choices, teacher priorities, roster memberships, at-risk designations, seat limits, shared room capacity, and student separation rules, then assigns everyone a seat. Manual registrations are never overwritten, and admins can run Autoassign on demand or reshuffle automated placements at any time.
No spreadsheets. No chasing students who forgot to sign up. No period that starts with anyone unaccounted for.


The scheduling engine behind your MTSS and RTI process
Get students help during the day, not after it
Flex moves intervention into the school day, when every student is already in the building. Teacher requests for 1:1 and small group sessions outrank student sign-ups, admins can assign must-attend sessions, and every intervention is documented with attendance you can pull by activity, student, or date.
At Dickinson High School, where 3,810 students use Flex for daily flex time, Biology STAAR retester passing rose from 25% to 76% in three years.
"If certain students are falling behind, I can find out quickly, go on my computer, log into Flex, type in their name, and draft them for the following day."
One flex period, every student
Support at one end, acceleration at the other
The same 30 minutes covers both ends of your roster. A student retaking Biology is in a small group with the teacher who drafted them. A student who already passed is in a dual credit block, a second science elective, a robotics build, or a college essay workshop. Flex time stops being catch-up time and starts preparing every student for college and career.
Students browse open sessions and choose how to spend their flex time. Teachers and admins set what's available, who's eligible, and which placements can't be traded away. Choice builds engagement. Priority protects support.

What school leaders are saying
Trusted by more than 1,000 schools
"First semester, I had students making 30s and 40s on their chemistry tests. Now I'm calling their parents telling them to take this kid to get ice cream because she aced the last four exams. Securly Flex is the most 'no child left behind' thing we do."
"Securly Flex has helped us achieve one of our key goals as a school: to make a big school feel small by building positive relationships among teachers and students, and students with their peers. Securly Flex has been a very useful tool to schedule academic enrichment and remediation, as well as a variety of extracurricular and co-curricular clubs"

"We were never satisfied with how RTI was managed until we used Securly Flex. After less than one year of use, we know that Flex meets all our needs."
