New documents are suggesting that weak support from teacher unions was a factor in the state's failure to win money in the Obama administration's $4.35 billion "Race to the Top" school reform grant competition.
The U.S. Department of Education on Wednesday released "scorecards" for applications submitted by California and other states that applied for grants in the competition's second round.
State education officials have expressed disappointment that California was not among the 10 winners announced Tuesday. Nine states and the District of Columbia will share $3.4 billion.
California placed 16th of the 19th finalists, scoring 416 out of 500 possible points.
The state also lost points for not fully implementing a data system to monitor student achievement over time.
