Yes, ye just moved in February and DS1 had to move schools. I was worried how he would do, with making friends, with switching to a new teacher with a different teaching style than he's had all year, etc. He actually did amazing with the move! He loves the new school, absolutely loves his new teacher, and has made new friends already. There were differences with what each school was focusing on, especially sight words. The two schools were using different lists, so we had some catch up to do on a few words that hadn't been on his lists at the old school. The old school basically just had them study flash cards with the words, and the new school has a whole rotation of words, sentences to practice fluency with the new words, combination of both, etc. that he has done well with, although it was an adjustment getting used to that difference in structure.
If the move will be during school time of year, I would suggest asking his teacher for his most up to date testing scores (reading, comprehension, letter recognition, sound recognition, shapes, etc) and any information she has on his progress to be able to give the new teacher so he/she can see where your child is placementwise right away. If there is an IEP, make sure you get a copy of it for the new school and follow up that it gets transitioned. My son has a speech IEP, and it took a month after the move to get it fully transitioned to his new school.
