* Check the school's website: Most schools post their academic calendar online, which will clearly show the last day of classes.
* Look at the school's calendar: Many schools provide a printed calendar at the beginning of the year.
* Contact the school directly: Call the school office or send an email to inquire about the last day of school.
* Check with your child's teacher: Your child's teacher will likely know and can confirm the date.
In short, you need to look at information specific to the particular school you're interested in.
