Let me tell you what happened to us.
I met a "wonderful" teacher while my oldest was a preschooler. I requested her and he was put in her class. She even had awards and accolades for being so good. I was elated.
Come to find out she had a K-1 program. She tried to teach the children Japanese and all about the Japanese society, in kindergarten.
Her teaching style was very Montesorian, not bad for some kids. Just not mine.
MIne was not taught the basics of HOW to read, just what the words said. She didnt; believe in Phonics. I found out in the middle of the year. She had no real discipline for difficult students, She thought counting in Japanese was more beneficial than counting in English and she missed some very key days, Valentine's Day being one, for some award in DC.
She scoffed at parents who were "difficult", that woud be me, because I wanted to see academic porogress and there seemed to be none.
She was not Japanese, she was awarded a grant for this program which in the end, after 5 years, was deemed a failure.
THE teacher that all the parents were scared of and warned me against had every one of her students reading at a 2nd grade level in Kinder. She had them all hitting their benchmarks and higher. She was a strict disciplinarian. Her children were organized and well behaved, as organized and well behaved as a 5 yo can be, much more so than our class. At the beginning of the year I was so happy to not get the "schoolmarm" and get the Japan class. What a mistake.
Since that time I have not requested any teachers for my kids. We have had some doozies and we have had some of the best teachers I have ever known. I let the schools piick my kinder teachers then I worked very closely with the K teacher to get the best fit for 1st grade. After my first fiasco I taught all my kids to read, count over 100 and add before Kinder.
I now homeschool my two youngest.
