ABC/AYP

What is your level of understanding of

ABC Growth?

A. I TOTALLY get it and can explain it to others.

B. I think I get it but cannot explain it to others.C. I’m not sure how growth is figured but I have

some ideas.D. I’m clueless.

Where did we go from here?

•Set up data meetings with all schools to review student level data

•Identified students with needs and created a plan of action for students.

Carnegie and ClassScape…

VIP Students

What else?• Prioritized a list of students for intense tutoring that meet with

a volunteer every day and work in Carnegie online (middleschool)

• After school Carnegie Tutoring run by the teachers (middle school)

• Café meetings (Curriculum Assessment with Formative Evaluations) - Middle School

• Lunch and Learn (Elementary) - Teachers bring their datato the table

You mean there is more?• Data Notebooks - Elementary - Students documents attendance,

Formative data, writing samples, Accelerated Reader Logs

• Plans are made for each student and administrators know the data for their school

• FIT - Focused Instructional Time - Middle School

• Focused Reading - Elementary School

• Central Office supports the school

• Introducing EVASS to the schools in small bites…not dropping it on them like a lead balloon.
