Spin training—instruction in how to enter and recover from spins—used to be part of the private pilot curriculum. It was discontinued a few decades ago, in part because it was blamed for a drop-off in the number of students who completed their training and earned their private certificate. These days, the only required spin training is for the initial flight instructor certificate and one of the most popular line of airplanes—the Cirrus SR20 and SR22—come with an airframe parachute in lieu of demonstrated spin recovery capability.
