Definitely, go to the kindergarten info night and if you can visit the classroom during the day. Also two pieces of info/advice:
1. Jeffco has great schools w/outstanding teachers, but South Jeffco schools are wonderful schools mostly due to the amazing parental involvement. So no matter where you go, as long as you're involved with your girls' learning, life will be good.
2. Jeffco is facing tough budgeting decsions that will affect the classroom (class size, teacher cuts, supply cuts, etc.) Please understand that schools will continue to open enroll students into their school, but I predict there will be few children accepted into these schools. There has to be a balance between the expected number of children and the ratio of class size to staff for the next school year.
Good luck with your family's education endeavors:)
