Yesterday we told you about new features we've added to TR3 , our online database that let's you compare over 250 policies governing teachers in more than 100 school districts and all 50 states. TR3 is a treasure trove of data such as teacher salaries, class size ceilings and sick leave allotments, as well as rules on which teachers are laid off first, if peers have a say in teacher evaluations and whether teachers can get bonuses for student achievement.

但几乎没有抓the surface. TR3 policy topics include:

• Leave
• Dismissal
• Layoffs
• Evaluation & tenure
• Salary & benefits
• Calendar
• Class size
• Union rights and privileges
• Transfer and assignment
• Professional development
• General employment provisions
• Grievances
