It depends what you are looking for and where you are living. Last time I checked most 4 year olds were not in school. They were in pre-school. There are many choices: Henderson has the International School. Summerlin has the Meadopws, the Adelson School (the elementary school has a different name, but on the same campus). There are others all around. Just Google private schools in Las Vegas or Henderson. See what comes up. Call up the schools and see which schools fit your needs for your children.
