Stu Silberman suggested that I share elementary example to match yesterday's high school post.
Under Kentucky's new accountability system, schools are identified as proficient if their Overall Score is at or above the 70th percentile for schools at their level. Now that first year results have been released, it's easier to illustrate what goes into the Overall Scores and the proficient classification
To begin, each school now receives an Overall Score on a 0-100 scale. For elementary schools, 100 will mean that all students are on track to being college and career ready and they are all making typical or higher growth. Here's the actual example, showing the school's Overall Score of 62.5 and the three components that go into it:
The 73.1 for Achievement shown above is calculated from the students' performance levels in five subjects:
The 46.5 for Gap is also calculated from those five-subjects performance levels, using data only for students in groups that have historically been underserved:
Finally, the 66.6 for Growth reflects the students making typical growth in the two subjects tested more than once in high school:
In future years, the plan is to add program review results and professional growth and evaluation data to the Overall Score calculation. As that happens, the 70th percentile cut point will be adjusted. Once the full formula is in place, the state regulation calls for the 70th percentile to be recalculated every five years.
Added note: I've treated the school above simply as an example to help illustrate the main elements involved in being classified as a proficient school, using one of the four elementary schools with an Overall Score of 62.5. Though my purpose is to clarify the process rather than focus on a particular school, I'll satisfy any reader curiosity and mention that charts above show data from Madison County's Waco Elementary.
