Earlier this week City Schools Decatur had its 5,000th student register in grades K-12, by far the most in the district’s 113-year history. That number will likely fluctuate over the next few weeks before CSD publishes its first official 2016-17 count in October.

Last August CSD shattered its previous high of roughly 4,200 students in 1970.

Though an all-time high, the number may actually signal a slight decline in the district’s growth trends of recent years. CSD enrollment has jumped eight to 12 percent each year from 2009 through last year. The final official 2015-16 count taken last March was 4,676, so the new number represents a 6.5 percent increase.

Superintendent David Dude is still waiting on updated projections, but various forecasts over the last two years anticipate enrollment swelling to anywhere from 6,300 to 6,500 by 2020-21, and that’s without annexation.

CSD will also open Monday with all-time high of 34 trailers on five of its eight K-12 campuses. Ten of those are at Decatur High and 12 at Renfroe Middle.
