4/10GreatSchools RatingParent Rating AverageAs a parent I wanted to visit my sons math class, so I stopped in at the front office and made my request, she then called my son math teacher and she ok the visit. I was brought down to the math room[180] meet the math teacher before the class started,after couple minutes a staff member came to the room and said that this teacher had a meeting before her class, now the class was to start at 9:09 and the time was about 9:05 I thought this was strange. After a couple Minutes Co. principle Mendonsa came in the class room and told me that I had to leave, now I had received permission at the front office and a teacher herself HUGE RED FLAG. Now if the front office or the teacher had ask for me to come back another day that would of been fine. It looks to me that they are hiding something,shame on them that they can't act in a honest way, after all what are they teaching the children ?????????????Parent Review9y ago - Sanderson Academy
