What type of change is being implemented for the kindergarten program?

Increasing the duration of the school day for the kindergarten program reflects an intentional change aimed at enhancing the educational experience for young learners. This type of change can provide students with more time for both structured learning and unstructured play, allowing for a more well-rounded educational approach. Longer school days can accommodate a variety of developmental activities and ensure that core subjects are covered comprehensively while still allowing time for socialization and exploration, which are integral to early childhood development.

The other options present scenarios that do not align with typical educational enhancements. A decrease in enrollment numbers does not indicate a positive change in the program; instead, it can signify challenges that could negatively affect the program's viability. Reducing the focus on core subjects would be detrimental to educational standards and student preparedness. Lastly, while introducing extracurricular activities is beneficial, it does not inherently reflect a change in the structure of the kindergarten program itself, as the extension of the school day directly alters the time allocated for learning and development.
