Having coached Jr. Rifle and sent my daughters...
through beginning rifle and hunter safety.
The first should be a basic firearms training course, either hunter safety or beginning rifle / pistol course.
Here you will get the safety lessons and principals of sight alignment and trigger control and breathing.
When the person is comfortable with the firearm of choice, then try standardized course of fire; e.g.: bulleyes shooting, bowling pins, silhouette, etc.
The they should consider advance training courses within local area.
Best to "Keep it super simple" for starting.
