The final model included teacher as a random effect, and fixed effects were pretests (both WP composite and WRAT
3 computations) and special education status (at L1) and cohort and treatment (at L2).
As revealed with one-way analyses of variance (ANOVAs), the groups were comparable on WRAT Arithmetic, WRAT Reading, WASI Vocabulary, WASI Matrix Reasoning, and WASI IQ.

It is used because it takes into account the approximate standard error of measurement (SEM) on the WRAT
of between 3 and 5 points; that is, with a discrepancy of 18 points and a SEM of approximately 3 points, the "true" discrepancy between earned scores is free to vary between 15 and 21 points, which is roughly a difference of 1 to 1.
The RockOn, RockSat, and WRATS programs are supported by the NASA Sounding Rocket Program.

In the WRATS program, 20 high school teachers from Virginia, Maryland, Delaware, Pennsylvania, Tennessee and the District of Columbia will learn about the dynamics of rocketry and the science gained from suborbital sounding rockets to reinforce STEM concepts they teach in their classrooms.
and WRATS provide a unique experience for students, faculty and teachers to understand the importance of a sounding rocket suborbital launch and the value of science that is collected," said Joyce Winterton, senior advisor for education and leadership development at Wallops.
The inaugural WRATS program will give high school teachers a technical flight experience to reinforce STEM concepts they teach in their classrooms.
