istation’s Indicators of Progress ‐Advanced Reading

• An entire class can complete ISIP on computers simultaneously. 

• All children complete assessment in approximately 20 minutes.

• Teacher reports on ALL students are available immediately.

• Reports will allow teachers to quickly see where to direct instruction.

Purpose of the ISIP IRT study

• To determine the psychometric properties of the ISIP Advanced Readingitems using Item Response Theory (IRT). 

• These items measure student ability in four key domains of established readers: word analysis, vocabulary, fluency, and comprehension.

Study Results

• The IRT results from this study will allow researchers at SMU and istation to determine difficulty and discriminabilityparameters for the items. 

• Allows tests to be tailored to each individual student’s performance.

• The final result will be a computerized adaptive version of ISIP, appropriate for 4th through 10th grade students.

Study Implementation

There will be one SMU School coordinator at each school to monitor students and answer questions.

The entire study at each school will take approximately:

Six 45‐minute sessions

Nine 30‐minute sessions

Our schedule follows the students’ schedule.

If sessions are missed because of holidays, assessments, field trips, etc… then we have to make them up.

Study Sessions

“Test Bucket”• Comprehension: 45 sec intro + 2 passages = 

• 8 minutes, 45 seconds• Spelling: 60 sec intro + 10 items = 

• 3 minutes, 30 seconds• Vocabulary: 60 sec intro + 8 items =

• 3 minutes, 40 seconds

• Fluency items will not be included in this study. 

• Children will take “test buckets” until they have taken all assigned items.

Total Study Items

Every grade will take approximately 150 spelling, 120 vocabulary, and 30 comprehension items.

Each grade will take approximately 15 spelling, 12 vocabulary, and 3 comprehension items (10%) of the items from the grade below.

Only third graders will take ISIP Early Reading items 40 spelling and 30 vocabulary items (no comprehension).
