The 2018 four-year cohort graduation data are up on the VDOE Web site.

For a discussion of the ways VDOE manipulates the data, see this post. To the point here, the state’s “on-time” rate boosts the numbers, especially for those divisions willing to misclassify students as handicapped. Now we have an additional boost: “Credit Accommodations” now allow students with disabilities who previously would have pursued a Modified Standard Diploma to earn a Standard Diploma.

The data below are the “federal” graduation rate, the sum of standard and advanced studies diplomas divided by the cohort size. Because of the Credit Accommodations, the numbers do not compare directly to data from prior years. (Calculations from earlier data suggest that this manipulation boosts Richmond’s federal rate by about 5% and the state rate by about 1.3%)

The cohort data also include dropout numbers.

Let’s start with some division graduation and dropout rates.

By nearly a 2:1 ratio, those Richmond diplomas are standard, not advanced studies.

The Richmond numbers are driven by three of our general population high schools, with the other two tagging along.

We have the worst graduation rate in the state.

Also the worst dropout rate.

Finally, here are the lists of the worst schools in terms of graduation rate,

and dropout rate. (The “#NA()” entries are cases where groups of <10 students invoked VDOE’s suppression rules.)
