Transcript Determining Dual Discrepancy Using The PED Short Cycle Test

Determining Dual
Discrepancy for SLD
Using The
PED Short Cycle
Test Results in K-3
Donald J. Frazier, Ph.D.
Locating The State Test Bank Data
• Go to the NM PED Website
• Select Special Education
Department on the A to Z
Menu
• In the SPED Search Box, type
in Dual Discrepancy
• That will lead you to a web
page with a number of different
entries
• The first two entries are the
current short cycle results for
fall 2009 and spring 2010.
• Find the MAPS Data for Math
and Reading/Language Arts
for each grade level (K-3)
• NOTE: The data used will be
from the year prior to the dual
discrepancy assessment.
Thus, for students referred
during 2011-2012, the data
used will be from the 20102011 school year.
The 2010-2011 data will be
listed by the start of school in
August.
Kindergarten – Math (Factor 1)
Fall 2009 scores
MAPS - Kindergarten
MAPS – 1st Grade
Mean = 141.4
1.5 Standard Deviation = 17.76
Mean = 158.3
1.5 Standard Deviation = 20.45
Cutoff = 123.6 or below
Cutoff = 137.9 or below
MAPS – 2nd Grade
MAPS – 3rd Grade
Mean = 173.7
1.5 Standard Deviation = 17.31
Mean = 188.2
1.5 Standard Deviation = 18.48
Cutoff = 156.4 or below
Cutoff = 169.7 or below
Examples
What can you make of these scores?
• Student score on MAP kindergarten Math was
129
• Student score on MAP 1st grade Math was 126
• Student score on MAP 2nd grade Math was156
• Student score on MAP 3rd grade Math was 182

NOTE: Students who took only one of the tests must NOT be included in the analysis
•
First, obtain the mean and standard deviation of the difference scores
•
•
•
MEAN Difference = 60.6 of all students in this grade who took fall and winter EPS Reading test
SD = 58.3
1.5 SD (1.5 X 58.3) = 87.5
•
•
Slope Cut Score For Grade = 60.6 – 87.5 = - 26.9
Thus, the individual student would need to have a growth rate that was a decrease of -26.9 or more.
