Description¶

The guide encloses Measurement Rulers for reading and math that show how to relate specific test results to the content of the ITBS. Productivity profiles use a new vertical scale from 0 to 100 created for this study; the rulers let users "roughly translate a score into content material by looking at these measurement rulers." The right-hand side of the profile marks national norms for fourth, sixth, and eighth grades.

Design Implications¶

Context¶

Requirements¶

• Users must consult the attached Measurement Rulers to interpret the 0-100 profile scale

Constraints¶

• The scale translation is approximate: users can roughly translate a score into content material

Target Learners¶

• Chicago public elementary school staff reading their school's productivity profiles

Target Learning Goals¶

• Interpreting school reading and math test results in terms of the content students mastered

Claims¶

• Less than half of Chicago elementary schools keep pace with ITBS grade-level content expectations during the last three years of elementary schooling [+W]
