The new Legislative Analyst’s Office projection for 2017-18 includes funding from Proposition 55.
State propositions extend tax on wealthy residents, fund a $9 billion construction bond and repeal English-only instruction law.
More than $75 million has been spent in an effort to get the three ballot measures passed.
Depending on stock market returns, it would generate $2 billion to $4.5 billion annually for schools.
Backers of extending the tax on wealthy residents also have yet to seal the deal.
