LOUISVILLE, Ky. (WDRB) -- The first day of school is over for kids in six different counties and Jefferson County Public Schools, the largest district in the state, welcomed back nearly 100,000 students Wednesday morning.

The district says there were no big issues reported as of 4:00 p.m. Wednesday afternoon and the last student was let off the bus at 6:14 p.m. -- 21 minutes faster than the first day last year.

With smiles on their faces, elementary students walked out of Lincoln Elementary School Wednesday around 3:45 p.m. with the first day of school officially in the books. Some families said they spent Tuesday night preparing.

"So we read some books and we got ready and she was ready to go," said Wanda Peck.

Her five-year-old daughter, Fern, just started kindergarten at Lincoln, a performing arts magnet.

"It's just a fantastic opportunity for my daughter to get up and move around, she has a lot of energy and it's just a beautiful school," said Peck.

The first day was just as exciting for Fern, who stayed busy all afternoon.

"I like to do lots of things,” said the first-time kindergartener. “First I got to school, and well, then we started doing some stuff, and then we went to the bathroom."

JCPS says 97,000 students went back to class at more than 150 schools Wednesday.

"It's always a butterfly day," said Chenoweth Elementary principal Penny Deatrick.

She’s lead the school for 16 years now.

"I can't even begin to describe the amount of planning that goes into a smooth first day," said Deatrick. “Right now we are hiccup free. Things seem to be very smooth. Our parents were wonderful -- they cooperated because the line is really long. The first few days of school because we have to iron out all those kinks."

As for the 950 bus drivers in the district, JCPS says approximately 50 buses were late for elementary pick up due to delays in their high school routes.

Despite that setback, the last student was dropped off earlier than last year, according to JCPS.

"Lots of preparation went on and it all seem to have paid off," said JCPS Superintendent Dr. Donna Hargens.

Hargens was up and ready at 5:00 a.m. visiting different schools all day. The first day may be in the books, but she says they're just getting started.

"Now it's just lets redo this, what, 174 more times and have a great day for the rest of the school year."

But not every student is back in school at JCPS quite yet; 4,400 preschoolers head back Aug. 26.
