One of my boys is 2E, and our school uses a STAR test for reading. His scores go up and down 1/4 to 1/2 a grade level each time. When I expressed concern about that to the teacher, she said every child's scores vary like that, but as long as they're on a strong upward path, there's no concern.
My other son, who has dys scores, varies as much as a grade level (but his start 7 grade levels ahead), and it's not a concern.
I would try to look at the trend, rather than the actual score.
PS I also wanted to add that being tired really affects my 2e son's scores, as does his mood and what he's eaten. When we had a private tutor, she would try to only test him when she could tell he was having a great day, and that really affected his scores. Obviously that can't happen in a school setting.
