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.

Question after Handout:In 3rd grade math, the scale score of 352 is
Level 4. If a child made a 357 in the 4th gradein math, what level would they be?
7. Each student has his/her own individualized

Coefficients were set when the New Formulas were developed
They help account for the “regression to the mean”

If Jeff hits a 354 for Reading in 5th grade,what does that mean for his growth?
Academic Change
Actual C-Score(on current assessment) - Predicted C-Score = AC
Academic Change
If the AC is greater than or equal to
Then - the student has met

Expected Academic Change (EAC)
If the result is greater than or equal to
Then – the school met it’s
AKA:Met Growth
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.
