How much would achievement rise if students were on task ten more hours a week?
Every campus loses instruction time to low-level disruption. Academics and discipline are the same problem.
Empowering school leaders. Supporting teachers. Championing kids.
Karissa Flieth brings Time To Teach classroom management training to K-12 schools and districts, with practical strategies your teachers can use right away.
Karissa has spent 25 years in education as a classroom teacher, a principal and a curriculum coordinator. Now booking the 2026-27 school year.

Classroom management is one of the most measurable levers a school can pull.
These are the figures principals bring to the board. Each one has a source.

Four questions principals are asking right now
If one of these sounds like your campus, the conversation is worth having.
What could you accomplish if discipline challenges dropped by seventy percent?
Strong instruction without a working management system stays undelivered. Karissa puts the system in place, and your teachers carry it forward.
Is teacher retention starting to keep you up at night?
Classroom management, or the lack of it, is the most cited reason educators leave the profession. The fix is teachable, and it is fast.
Did your last PD investment change Monday morning?
Most professional development inspires for a day, then fades. Time To Teach is built around what teachers can use in their very next class period.
This training provided the best logical presentation, on discipline I've ever had in my 23 years of teaching. I have practical ideas I can use immediately.

What your teachers take home
After one day, every teacher leaves with the same playbook, ready for the next class period.
- How to detect and correct problems without stopping teaching
- How to avoid power struggles and set effective limits
- Fifteen desk arrangements for maximum performance
- How to teach students to behave in class and in social settings
- How to never give multiple warnings or repeated requests again
- How to firmly but fairly carry out disciplinary actions
- How to build trust with the most challenging students
A research synthesis of over 100 studies found that teachers' actions in their classrooms have twice the impact on student achievement as school policies regarding curriculum, assessment, or community involvement.

What teachers say after Time To Teach training
The classroom management seminar was one of the most immediately useful workshops taken to date. Even after 20 years of education!
I was going to retire this year, tired of all the nonsense and students who don't pay attention. This seminar has given me some great ideas to put into my classroom, I think I will be around a few more years. Thank you!
All the concepts and ideas presented were logical, practical, and had the best interest of all the students in mind. I really enjoyed my day and have a new outlook on classroom management. I recommend this seminar to anyone who works with children!
