An "adulting conference" this week allowed Kentucky high school seniors the chance to learn how to change a tire, how to cook and other basic life skills – things that they may not have learned at home or in classes.

A series of photos posted by Bullitt Central High School on social media shows students learning about personal finances, resumes and other essential skills at the event, which has drawn attention from local and national news outlets. The school is located south of the city limits of Louisville, Kentucky.

Students could choose to attend three workshops out of 11 total options, the school says. The workshops were held in cooperation with numerous community partners.

“I saw a Facebook post that parents passed around saying they needed a class in high school on taxes and cooking,” organizer Christy Hardin told Louisville's WAVE 3 News. Those skills are taught at school, she said, but the event gave students a chance to fill in gaps in their knowledge.

Changing a tire, credit cards and financing were among the topics covered at the conference, WAVE reports.

Some young people have left home and graduated school without having those gaps filled, according to a report this week from CBS New York, which documented a trend of millennials seeking out classes to learn basic life skills.

While attending a cooking class, 29-year-old Elena Toumaras told the station she's struggling with "simple things."

"I was so used to, when living at home, my mom always cooking,” she told the station.

An "Adulting School" in Portland, Maine, aims to use a new online format to teach millennials skills like conflict resolution, sewing and appreciation for art, the station says.

Students' financial literacy has been of particular concern to some experts.

In February, financial education in schools has stagnated in the U.S., with only 17 states requiring students to take classes in personal finance – a number that hasn't risen in years.

"The majority of U.S. states are failing our students by declining to offer these fundamental courses which are critical to their financial stability and security later in life," Nan J. Morrison, president and CEO of the Council for Economic Education, told CNBC.
