I was an early adopter of School Twist, which I discovered by word of mouth soon after I became the Director of a busy, suburban K-8 after-school enrichment program. Making the switch from paper registration forms was an immediate, and HUGE time-saver, (and getting rid of the paper catalog was a huge money saver). The integration with online payment processing saves us a lot of time and effort too (we were still using paper checks as recently as 2015, believe it or not).
With School Twist, each session gets easier to run, and it streamlines processes immensely. Running an enrichment program like this is is an enormous challenge and School Twist really helps to make it possible. I have to mention too: the level of support from JJ and his team was top-notch – they know what it is like to both organize and run programs like this, so are able to advise based on real-world experience.
