The missing charter aggregate data

June 8, 2013

As debate heats up over the performance of charter schools, it turns out that Delaware’s school performance data provides aggregate performance data for its districts, but not for all charter schools together, a virtual district sometimes informally known as the “Charter District.” There are reports that this data was once available on the DOE web site, but was removed.

A few days ago I put out a call for one or more volunteers to take the data for individual charter schools and to reconstruct a spreadsheet showing the missing performance for the “Charter District.”

Well, at least one volunteer did step up (not me), and the results are here. If you see any errors or think of a way to better present this data, please add your suggestion to the comments. This is just the starting point. This is a community project and is a work in progress, so we expect to be uploading new versions as improvements are made.

1. The spreadsheet [Updated 6/9]

2. An existing UD presentation with additional information on charter performance and demographics

3. And two charts with data from the spreadsheet:

    One quick observation from a quick glance at the charts ( and thanks for the great data!): the aggregate charter data moves pretty consistently with the aggregate Brandywine data. And guess what? Low-income #s are quite similar for those two “districts.” So as we’ve been saying, maybe the charter special sauce is largely about demographics–the handful of high-performing charters are the socio-economically “elite” ones, and overall they perform consistently with a district grp of roughly similar students. Much more work could be done to analyze this line of comparison.

    At first glance I thought that wow, Christina did really well among low income students. Then later I realized it was the number of low income students. Others may jump to the same conclusion; perhaps if a dark line separated the two types of data?

    Question: Red Clay’s District School Profile page includes its charter schools – are those schools included in RCCD’s column? Basically, are RCCD charters being counted in the charter column and Red Clay’s column?

    Great blogging, Mike!

    Pandora: There is no double counting. The district numbers are tallied by the DOE so RCCD includes CSW. The list of charter schools are only those that DOE granted, i.e., a DOE charter district. It would be easy enough to change.

    Spreadsheet updated.

    Okay… so Red Clay’s spreadsheet includes charter schools?

    What is the complete list of charter schools administered by districts?

    A quick glance (forgive me for not being familiar with all districts) at the DE school profile page leads me to… Red Clay administers 3 charter schools: The Charter School of Wilmington, Delaware College Prep and Delaware Military Academy.

    I looked at the other districts, but didn’t see any of them listing charters.

    Red Clay is the only district that administers its own Charter Schools.. However if HB 165 passes, I would think the Christina District should immediately “charter” their school for the deaf, charter the autism schooling program, and charter their alternative school, (and there is one more I’m missing)… all of which receive students sent in by other districts…. No reason they should suffer when everyone else is getting lots and lots of free money, exceptional benefits, and no oversight or accountability what so ever…..

    GRAB THIS! (before its taken down).

    I haven’t had a chance to look at it, but I would bet the excel spreadsheet is a gold mine. This data set is based on student geographic data that is not available to the public on DOE website, i.e., the public could not reconstruct this data if it were taken down.

    Clarification: the spreadsheet on kavips did not include CSW so this lead me to believe that CSW was included in Red Clay. However, when I click on the DOE data for Red Clay by school (10th grade, say, reading), CSW is not on the list. Also absent are Delaware College Prep and Delaware Military Academy (for other grades and tests). So I believe the district data complied on the DOE webpage excluded charters. This means the charter schools administered by Red Clay are not included in the spreadsheet. I think this is actually quite helpful and will make calculating stats for the charter district a lot easier. More later.
