  1. Understanding the New ABC’s Formulas Slide show originally created by Caswell County Schools Revised by Cathy Williams - Greene County Schools

  2. 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.

  3. Vocabulary Expected Growth Expected Academic Change High Growth High Academic Change

  4. 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?

  5. 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)

  6. 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

  7. 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 Math Gr 3 :  =(scale - 343.2)/9.700971= c-score Gr 4:  =(scale - 348.9)/9.460422 Gr 5:  =(scale - 353.7)/9.200000 Gr 6:  =(scale - 354.9)/9.697828 Gr 7:  =(scale - 357.8)/9.646732 Gr 8:  =(scale - 359.2)/9.208106 READING Gr 3:  =(scale - 338.6)/11.900000 Gr 4:  =(scale - 345.2)/10.100000 Gr 5:  =(scale - 350.0)/9.400000 Gr 6:  =(scale - 352.9)/9.600000 Gr 7:  =(scale - 355.6)/9.200000 Gr 8:  =(scale - 358.4)/8.800000

  8. 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”

  9. Figuring Erik’s ExpectedReadingC-Score -  = (6th + 7th)/2 Scale Score = 355 Level 2 x =  2 =

  10. Figuring Jeff’s ExpectedReadingC-Score -  = Scale Score = ____Level__ x =  2 =

  11. 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 Math Gr 3 :  =(scale - 343.2)/9.700971= c-score Gr 4:  =(scale - 348.9)/9.460422 Gr 5:  =(scale - 353.7)/9.200000 Gr 6:  =(scale - 354.9)/9.697828 Gr 7:  =(scale - 357.8)/9.646732 Gr 8:  =(scale - 359.2)/9.208106 READING Gr 3:  =(scale - 338.6)/11.900000 Gr 4:  =(scale - 345.2)/10.100000 Gr 5:  =(scale - 350.0)/9.400000 Gr 6:  =(scale - 352.9)/9.600000 Gr 7:  =(scale - 355.6)/9.200000 Gr 8:  =(scale - 358.4)/8.800000

  12. If Jeff hits a 354 for Reading in 5th grade, what does that mean for his growth? Figuring Jeff’s ExpectedReadingC-Score -  = Predictor = (Predicted C-score * Standard Deviation) + Mean Scale (.816*9.4)+350 Scale Score = 357 Level 3 x =  2 =

  13. Academic Change - Actual C-Score (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)

  14. 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

  15. 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

  16. Carnegie and ClassScape…

  17. VIP Students

  18. 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

  19. 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.
