The Jackson County Spelling Bee champion spelled his word correctly in the first oral round of the National Spelling Bee, but he  failed to make the quarterfinal round.

Brent Henderson got to stand on stage at the Scripps National Spelling Bee and correctly spell "spelunking" Thursday morning. But the winner of the Jackson County Spelling Bee was not among the quarterfinalists advancing on to the third round.

This is the first year for the seventh grader at Moreland Ridge Middle school in Blue Springs to attend the National Spelling Bee in Washington D.C. In total, there are seven students from Missouri competing. Only Corrine Yap of Sedalia advanced to the quarterfinals. In Round 3 Yap correctly spelled "contumelious."

Only 100 students of the 288 who started the bee moved on to quarterfinals. Those who advance were determined by a combined score from the written test taken in round one and the scores from round two.

The quarterfinals began at 1 p.m. Central time and were shown live on ESPN360.com. The semifinal rounds begin at 10 a.m. Friday and will be shown live on ESPN, Comcast Channel 13.

The finals are at 7 p.m. Friday and are shown live on ABC, Comcast Channel 12.
