What changed between versions

As Passed by the Senate Substitute (H-5) · 6 edits
MODERATE
The bill was substantially rewritten from the Senate version to a House substitute version, changing the scope of amendments from dozens of sections to just six specific sections. This represents a major reduction in the bill's scope, focusing on specific appropriations and payment schedules rather than broad legislative changes across the state school aid act.
Scope change
The bill's scope was significantly narrowed from amending over 100 sections of the state school aid act to only six specific sections (11, 17b, 201, 206, 236, and 241).
SCOPE

Reduced the number of amended sections from over 100 to just six specific sections, indicating a major simplification or refocusing of the legislation.
