I have a lifetime credential and more than 30 years of teaching experience.
I would find a LAUSD school with empty classrooms or a unused portion of a church or a center in order to keep the rent low.
I would find new, inexperienced teachers, even some without a credentials, who would accept the low pay.
I would get some corporations to donate old computers.
It would be easy to attract students whose parents are unhappy with their home schools.
If I am fortunate I can involve the Billionaire so-called reformers, who have their hands and dirty feet in public education and have investments in charter schools. These so-called reformers want to change, not reform, public education as an inducement to parents to put their children in to charter schools.
They are in it for the money as charter schools are investments.
In order to make money they pay the teachers low salaries.
Here is a link to a Washington Post article that describes the salary structure for Washington area charter schools.
Are charter schools truly about education or are many of them truly about profit?
