Establishes four-tier teacher and principal performance classifications (highly effective, effective, developing, ineffective) with academic progress data accounting for at least 50% of evaluations, replacing previous 33-50% range.

Allows continuing teachers designated in lowest two performance classifications for two consecutive years to be converted to probationary status, subject to dismissal procedures.

Requires school districts and charter schools to allocate at least 50% of performance-based classroom site fund compensation to individual teacher performance evaluations, increased from previous 33%.

Removes requirement for 70% teacher approval of performance-based compensation systems and eliminates restrictions on teacher transfers based on principal performance classifications.

Modifies teacher evaluation timelines and preliminary notice procedures for inadequate classroom performance, requiring performance improvement plans before dismissal notices can be issued.
