12. Implications President Bush in 2006 State of Union Address Proposed: Recruitment of 30,000 New Math/Science Teachers But, in 2004-05 alone….. - 26,400 Math/Science Teachers Left Teaching - Of them, - 7,000 Retired - 14,000 left due to dissatisfaction or to pursue another job - 25,000 Moved to Other Schools - Of them, - Four times as many moved to low-poverty as to high-poverty schools
