Understanding the New ABC’s Formulas

Slide show originally created by Caswell County Schools

Revised by Cathy Williams - Greene County Schools

slide2

ABC/AYP

What is your level of understanding of ABC Growth?

I TOTALLY get it and can explain it to others.

I think I get it but cannot explain it to others.

I’m not sure how growth is figured but I have some ideas.

I’m clueless.

Vocabulary

Expected Academic Change

Scale Scores

See Handout

Question after Handout:

In 3rd grade math, the scale score of 352 is

Level 4. If a child made a 357 in the 4th grade

in math, what level would they be?

slide5

Don’t worry….blonde directions are coming…

Each student has his/her own individualized

Predicted Change Score

Or Predicted C-Score

Or Predictor Score

  • Based on the average of their

Actual Change Scores

over the two previous assessments

(uses 1 year if 2 are not available)

slide6

Actual Change Score Formula

(Student’s Developmental Scale Score – State Mean Scale Score)

Standard Deviation

Standard Deviation & State Mean are set in the 1st year of a test edition’s implementation

354.0

(Erik’s Current (2008-2009)7th Reading SS)

- 355.6

(State Mean for 7th Reading)

-1.6  9.20

(7th grade Reading Standard Deviation)

-.174 - Erik’s Actual C-Score

Predicted Change Score Formula

predicted C- Score

  • Each student has an individual
  • Based on the average of the

Actual C- Scores

on their

two previous assessments.

(uses only 1 if 2 are not available)

Average Two Previous Assessments C-Scores (ATPA)

X

Coefficient = Predicted C- Score

  • Coefficient for 2 years of data = .92
  • Coefficient for 1 year of data =.82

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?

Figuring Jeff’s

Predictor = (Predicted C-score * Standard Deviation) + Mean Scale

Academic Change

(on current assessment)

AC

Academic Change

=

Predicted C-Score

0.00

If the AC is greater than or equal to

Then - the student has met

Expected Academic Change (EAC)

slide14

School Level

Expected Academic Growth

  • = Average of all eligible student’s Academic Growth
  • If the result is greater than or equal to

0.00

  • Then – the school met it’s

Expected Academic Change (EAC)

AKA:

Met Growth

slide15

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 Math and ClassScape at Greene County Middle courtesy
    • of JoAnn Pennington, Assistant Principal
slide18

What else?

  • Prioritized a list of students for intense tutoring that meet with
    • a volunteer every day and work in Carnegie online (middle
    • school)
  • 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 data
    • to the table
slide19

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.
