Assembly Bill 1092 mandates that each school board in Wisconsin must include a minimum of 45 minutes of self-directed preparation time in teachers' daily schedules, or the equivalent of one class period, whichever is greater. This requirement is established by creating a new statute, 120.12 (30), which specifically addresses teacher preparation time. Additionally, the bill amends existing law by adding this new provision to the list of applicable statutes for first-class city school districts.

The bill also includes a provision regarding its applicability, stating that it will first apply to teachers affected by collective bargaining agreements or contracts that conflict with this new requirement upon the expiration, extension, modification, or renewal of those agreements or contracts. This ensures that the new preparation time requirement will be implemented in a manner that respects existing contractual obligations.
