The service originated from KET's studios at the O. Leonard Press Telecommunications Center, at 600 Cooper Drive in Lexington, Kentucky.
When it did so, the HD schedule relocated to the Kentucky Channel feed, and was expanded to include an additional hour of programming.
The subchannel went off the air nightly during the hours that the Kentucky Channel broadcast the PBS HD schedule.
Beginning in January 2009, KET ED ran programming on a 24-hour-a-day basis on Louisville's WKMJ through its DT3 subchannel, which in the present-day, carries the World Channel.
Unlike KET's other services, during the interstitials, KET ED showed various slides, often accompanied with the network's URL, and a toll-free telephone number, along with a digital clock showing the current time, as opposed to normal network promos, in between programs and/or videos.
The network-produced series, which launched in 1995, were mostly documentaries about mainly historic and/or natural places in Kentucky (i.e. Mammoth Cave National Park, Old Fort Harrod State Park, Fort Boonesborough State Park, Louisville Zoo, southern Indiana’s Falls of the Ohio), but the EFT series also took students (vicariously through video) to farms, museums, the Kentucky Center For the Arts, a dentist’s office, the Louisville National Weather Service forecast office,[8] and even the KET network studio itself.
KET ED also broadcast a package of 30 select episodes of Fat Albert and the Cosby Kids that were shortened to 15 minutes each and edited specifically for instructional use.
