Europeans have been "tracking" kids into vocational or academic education quite young for decades. Germany has other countries very envious of Germany's very successful apprentice/work-study programs.
The American argument against tracking has been "equal opportunity (to the supposedly superior academic track) for all", which is hypocritical bull since entire schools and school districts are underfunded to deny "equal opportunity" of any education.
About the ONLY expected change to US K-12 education will be the continued onslaught by the VRWC/BigCorp on K-12 to transform it into failing for-profit, under-paying, under-educating charter schools. The onslaught of killing teacher jobs to kill teacher contributions to teacher unions supporting Dems, of weakening/killing teacher unions, all with financial windfall of grabbing taxpayers' $Ts away from public schools to for-profit charter schools.
"non-profit" charter schools pay ty teacher salaries and get ty non-union teachers (very high churn), while outsourcing as much a possible to for-profit contractors.
iow, "non-profit" charters schools are a successful scam but an educational failure because education and students were never their objective.
America is missing 100Ks of welders. One solution:

For-profit prisons are very probably not interested in in-prison education and training since those programs have proven to reduce recidivism. The PIC is most interested in the keeping prisons full and recidivism as high as possible, "for profit". Corrupt police, mandatory sentencing, corrupts prosecutors and judges, absent mental health care, Repugs REFUSING any immigration reform, all combine keep for-profit prison very profitable.
