We do a great disservice to students if we require flight test standards before solo, especially when flight test standards trigger dangerously slow takeoff speed and dangerously fast landing speed. Early solo is a morale booster and taking too long to solo may cause capable students to quit. Delaying solo to cram in techniques unrelated to takeoff and landing, increasing school/insurance confidence, and increasing profits are poor educational strategies.
Extensive stall recovery practice has little practical application in the pattern where few recover from inadvertent stall. Teaching students to only pull on the yoke with wings level and zoom reserve airspeed would be much safer. Vx or Vy as appropriate is seldom appropriate and is too slow for safe takeoff and climb out. The three seconds average it takes to recognize the engine has failed is not going to work at Vx or Vy pitch attitude and no engine. Extensive stall practice gets the student comfortable with an out of ground effect airspeed that is way too slow below a couple thousand feet and is way to fast to land in ground effect. Loss loss, not win win. All turns in the pattern should be 1g energy management turns to target to prevent stalls.
Airspace away from the airport of solo has no bearing on the supervised solo.
Ground reference maneuvers requiring altitude maintenance reject the law of the roller coaster and demonstrate how not to fly at low altitude. Ground reference maneuvers do not teach wind management, but rather wind mismanagement. With the orientation away from the target we have mission drift. Energy management turns to target , rather than moose turns around the target should be taught. Rather than stupid S turns upwind of the road, we should teach upwind turns to align with the road or centerline extended. With bank limitations because of the erroneous need to maintain altitude, we teach how dangerous maneuvering flight poorly done can be. The safe energy management turn would allow ground reference turns to target in strong winds. Limiting bank angle and going home in moderate winds rejects learning to fly. It sends the absolute worst message about flying. Wind can be managed in a way that is safer than a no wind condition. Students should learn that the wind is our friend, not our enemy. It provides free lift on takeoff, next to ridges, and in uneven heating of the earth when managed.
The turns to target necessary for safe pattern work can be taught. High altitude orientation requiring altitude maintenance in turns at all costs too often costs all. This rejection of the safe dynamic neutral stability of the airplane has no place below 2,000.' All turns in the pattern should be 1g energy management turns.
Following the short and simple FAA regulations without ACS technique degradation would allow ninety percent of students to be safely soloed in less than ten hours. This is exactly what happened with those same regulations prior to PTS/ACS. I fear some students who would make really good crop dusters or airline pilots look critically at the system and say, "I don't need this." It is a stupid game we didn't play before PTS. It is a stupid game the military does not play. It violates good educational principals.
This is just a rant and will not change much...unless you, young instructor, learn to fly and teach the same. It is easy and can be done in ten hours. ACS can follow in record time. The student, and you, will only have to hold your noses a bit during test prep. Remember to take the +5 knots on takeoff and the -5 knots on approach. And a bit of deceleration on short final can be snuck in. Just have the student say, "got a bit slow on the bottom there but seemed to work out."

and here I thought the airplane didn't care about the wind
