I recently got an offer (5000 Euros per month after taxes) from one of the organization from Netherlands and planning to move to Netherlands with a family of 3 including 3.6 years old kid, I've already gone through Numbeo and found most of the information required except getting my kid enrolled into International school, after googling around I found that International school charges way high than Public schools (which is almost free) it's like 6000-15000 Euro/year.

Are there any cheaper international schools, if yes, how can i get my Kid enrolled into one, any information will be a great help to me.
