As a consequence of the pandemic in 2020 we split those carts up and went one-to-one. So that was really what allowed us to when we had to go to remote learning the fact that we had all of those carts and that we had a fleet that really could have gone one-to-one if we needed it to. We ended up needing it to in order to continue teaching and learning at that time. And so we moved to putting all the iPads in grades K through two Chromebooks in three through twelve one-to-one at the elementary school. Generally the students do not take those devices home sometimes in fifth grade or in fourth grade. There may be some movement towards students taking devices home. And then we maintained some specialized devices in some teaching and learning spaces. So our project Lead the Way courses had some different devices. They needed more powerful devices in order to do some of the work. This cycle then aligns somewhat with the life cycle of our devices. So we cycle devices out of the fleet every four to five years. So you'll see that like the 2016 to 2020 to now we're at 2025. We're sort of paralleling the life cycle of devices. So it's a good time for us to be studying this to make a recommendation to you as to what we would want to move forward with and what are our needs within our teaching and learning spaces now as opposed to where we've come from through the pandemic.
