Score Change

Interpretation

 

 

 

 

Increase

Decrease

The increase in the GSVs suggests that the student’s

 

 

achievement skills have improved. The decrease in

 

 

standard scores indicates that the student’s peers

 

 

improved even more during the same time period.

 

 

In other words, the student improved but at a

 

 

slower rate than his or her peers.

No Change

Decrease

The consistency of GSVs across testing sessions

 

 

indicates that the student has not shown growth or

 

 

decline in the achievement area. The decrease in

 

 

standard scores suggests that during the same time

 

 

period, his or her peers’ skills improved.

 

 

 

 

Note: This table includes the most likely combination patterns of change for GSVs and standard scores. Less likely combinations (e.g., GSV scores decrease, standard scores increase) are intentionally omitted.

Score Reports

111111111

Three score reports are available: the standard score report, the parent report, and the GSV Charts report. A summary of the score report options for each report type is included in Rapid Reference 3.5. With the exception of GSV charts, the standard score report includes all of the reporting capabilities discussed in this section. The parent score report is a simplified report that provides subtest descriptions and summarizes subtest and composite performance. The parent report is intended to facilitate a discussion of assessment results between examiners and parents/guardians. The GSV Charts report only includes GSV charts and tables. The only way to access the GSV Charts report option is to select two or more WIAT-III assessments for an examinee and then select Generate Report.

Q-global (as well as the original Scoring Assistant) performs all of the basic scoring conversions and calculations and provides tables and graphs of the examinee’s performance. Raw scores are converted into various derived scores (e.g., standard scores, percentiles) for subtest scores, supplemental subtest scores, and composite scores. There is no need to look up weighted raw scores when using Q-global. Always enter raw scores for Reading Comprehension and Oral Reading Fluency. The raw scores will be automatically converted into the weighted raw scores before calculating the derived scores.
