Types of indicators
Types of Indicators

  • Subject-IPI – The transformation of a valid achievement level in a particular subject

    • CMT & CAPT : {100, 67, 33, 0}

    • MAS & Skills Checklist: {100, 50, 0}

  • Subject-SPI – The mean of subject-IPIs for a school (goes across grades)

  • IPI – The mean of a student’s subject-IPIs

  • SPI/DIP – The mean of a school’s/district’s IPIs


The 3 cap
The 3% Cap

  • The target is Goal and is applied by subject

  • 1% of Skills Checklist Users

  • 2% of MAS Users

  • A combination of these not to exceed 3%

  • The overage, selected numerically by SASID, is converted from a 100 to a 0.

  • Developing a monitoring system to flag over-use.

  • The average of a district’s worth of IPIs is the DPI


Participation calculation
Participation Calculation

  • Subject participation (of participation-included students) is the ratio of non-absent to total.

  • SPI and DPI participation rates (of participation-included students) are the ratio of the number of students with at least one valid test score to total.

  • SPI and DPI participation rates are higher than subject participation rates
