I believe the European school system should be looked at in a serious way.
Start streaming kids according to intelligence, aptitude, skills and interest at age 14-16.
Advanced academics for those going to University
Trade school prep for those interested in trades
Military training for those interested in joining the armed forces
Advanced music for those who exhibit talent and musical aptitude
Basic Life Sciences for those who show no interest in the above or come up short on academics.
Those students get trained in basic healthcare and first aid, personal health and hygiene, shops classes, personal finance , cooking
Life skills like fishing, farming camping, environmental stewardship.
Make school interesting and play to a students strengths
