Notes on the collection and use of the data reported by the ECF calculator

In theory, virtually all states are reporting school performance data to the public.  In fact, only a few report in a way that enables public users to confidently determine which schools are doing the most for their students.  

States differ greatly with regard to transparency.  Many appear to be concerned only with communicating school performance data to educators, not the public or elected officials. Although data may be available online, considerable technical expertise is required to locate it, much less organize it in a way that permits the user to make meaningful comparisons among schools. 

Without user-friendly access, the notion that a state’s schools are transparent and accountable to taxpayers is misleading.

Notes on data available in individual states 
Although terminology can differ, most states recognize four levels of reading performance: “advanced,” “proficient,” “basic,” and “below-basic.”  

The “advanced” and “proficient” levels are considered to be at or above grade-level and jointly referred to as “proficient.” The “basic” and “below-basic” levels are considered to be below grade-level and jointly referred to as “below-proficient.”

The measured levels of student reading performance referenced by these terms differ from state to state, thus users should avoid comparisons across states. Here’s why. For level-playing-field comparisons among, visit the Nation’s Report Card:  https://www.nationsreportcard.gov/profiles/stateprofile?chort=1&sub=MAT&sj=&sfj=NP&st=MN&year=2019R3 

For states that distinguish a greater or fewer number of reading levels, the data used by the calculator has been adjusted on the basis of the percentages of students at each performance level reported by the National Assessment of Educational Progress (NAEP).
