I have added numerous captions to the above video.
And the point of all this testing and expense?
To help justify eliminating tenure thereby enabling the firing of the higher paid teachers.
To help set the stage for low employee pay when schools are finally privatized.
To justify the privatization of public education.
To justify the state takeover of urban schools.
To allow shoveling money to test creators and publishers.
To help in the attempts to eliminate collective bargaining for public employees.
To destroy what little power the teacher's unions did possess.
Just my humble opinion!
