The key word in our state Constitution is "provision", and "ample provision" at that.
What we continue to fret over is better termed as "ensure success", and a huge and bloated system attempting to solve that has resulted in a generation of kids our businesses won't hire, and even speculate to foreign education systems to provide.
Our Constitution doesn't say "ensure success", a concept only a student can address.
Our P-12 teachers are well educated through a tough system, and meet ongoing requirements which are, if anything, too stringent. We can trust them to do their jobs.
Colleges/universities who whine about kids not being "ready" would do better to flunk them then to address readiness. At their level the kid is an adult, and needs to have already realized their responsibility. 
Second chance remedial should be its own thing, probably best handled through private business, who as paid services can better deal with those who lag behind and/or choose to game the system.
