### Determining Dual Discrepancy for SLD Using The PED Short Cycle Test Results in K-3Donald J. Frazier, Ph.D.

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 2010-2011 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

Mean = 141.4

1.5 Standard Deviation = 17.76

Cutoff = 123.6 or below

Mean = 173.7

1.5 Standard Deviation = 17.31

Cutoff = 156.4 or below

Mean = 188.2

1.5 Standard Deviation = 18.48

Cutoff = 169.7 or below

Mean = 158.3

1.5 Standard Deviation = 20.45

Cutoff = 137.9 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

### Factor 2 Example: Learning Slope Scores

STUDENTS Fall Score Winter Score DIFFERENCE

Student 1 1645 1690 + 45

Student 2 2005 2008 + 3

Student 3 1880 1942 + 62

Student 4 2076 2125 + 49

Student 5 1889 1915 + 26

Student 6 2109 2250 +141

Student 7** 1748 1730 - 18

Student 8 2067 2101 + 34

Student 9 1776 1941 +165

Student 10 1850 1949 + 99

Student 11 1921 --- -----

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.
