I can echo Pam's comments. I think she is spot on regarding the comments of both platforms.
I've used PowerSchool since 2003 in two districts. Georgia is about 1/3 PS and 2/3 IC.There is a lot of flexibility for customizations in PowerSchool. Also PowerSchool since 2015 has made some key acquisitions to broaden their offerings to the K12 sector. I think the product with their API has a greater ability to bolt on 3rd party applications. I'm not sure you have the same flexibility with IC.Hope those few things help.Best of luck!Roman
