Some TVAAS information I feel compelled to share follows. But first, repeat after me: "I love my students, I love teaching, and I'm good at it." We have to keep focused on the important things during these crazy times in education!
Last summer I did quite a bit of research about TVAAS, & here's what I learned:
I teach 4th & 5th pull-out ESL, so I share Reading instructional time when TVAAS matching rolls around in the Spring. Students are pulled out of their regular classes to attend ESL for about an hour a day. Since my students are pulled out at various times, the percentage of instructional time I claim for each student varies. For example, if a student attends one hour of daily Reading time in his/her classroom and one hour Reading time with me, the classroom teacher and I split instructional percentage & we each claim 50%.
In order for a teacher to have an individual TVAAS score (I'm talking about 4th & 5th grade now) the teacher must have the equivalent of 6 full-time students in the subject they teach in the same grade for a minimum of 150 instructional days. So if I have 20 4th graders and I claim 50% of their Reading instructional time I multiply 20 students times 50% which equals 10 students. I met the minimum of 6 students in the same grade, same subject, so now I have an individual TVAAS score. But remember, only if I claim at least 150 instructional days. I found this out because I claimed this wrong when I was on maternity leave, which is what led me to my research.
Here's where it gets interesting: If you have a student who performs significantly better than the state predicted, that student could be considered a "statistical outlier" & that student's score could be removed. I have had this happen more than once. I spoke to someone in testing who confirmed this. So basically, if a student does much better than expected, the state thinks something fishy was going on. In theory, students who perform significantly lower than expected could have their scores tossed out as well, although ironically, I've never seen this happen on my report. If you teach 120 students, tossing out a couple of scores probably won't make a big impact, but if you only have 20 students or less, it could definitely impact your growth score.
And the most interesting part of all...the state can and will throw out a score from the previous school year. So if Johnny does well in my class and terrible next year, Johnny's score could be thrown out from my previous year's score. And no one will tell you it's been thrown out.
Print your reports more than once a semester, and pay attention to the list of students whose scores were included.
And remember, you love your students, you love teaching, and you're good at it!
Tennessee parents do not want our children's teachers evaluated based on our children's test scores. This system is unfair to both the teacher and the student.
Tennessee parents demand testing transparency.
