There are alot of online information with international preschool but not the Thai preschool. Does any one know about Thai independent preschools?

Does they provide english program as well? I heard some Thai preschools are not bad and cost lesser than Inter preschool. Any recommendations in Lat phrao area?

Whats the pros and cons? it will be good that someone can provide me some links. Thank you

They indeed do provide English basics and are considered a basic need for most Thai children to enter private school systems.  Expect many of the schools themselves have such facilities, or work with them.  Our grandchildren attended a dedicated facility here in Lat Phao but it ceased operation a few years ago.  You might want to ask Thai with children in your area where they use.  Another approach might be to check from schools on Google Map and see if they have web sites or have a Thai speaker ask them for advise.  Even if they do not provide such service expect they will have a good idea of where there students come from.  Better private schools are competitive from grade one entry.

Try checking out Sarasas Romklao. It's a bilingual school and you may enquire to find what you're looking for.
 

Our grandchildren attended this school grades 1-6 and believe they also have pre-school at same location between soi 62-64 on Latphao Road.  It is a large Thai private school with swimming and good facilities.
