Rio's 2013 Phyz students are best ever

Rio's 2006 Phyz students held the top spot for six years. They scored as 72% Advanced or Proficient in Physics. With the STAR program's End Of Course (EOC) California Standards Tests (CSTs) winding down, this year's classes rose to the challenge. They will go down as Rio's best physics students ever, as measured by the state of California.

The physics students of 2006 had edged out those from 2001 by  single percentage point.

The physics students of 2013 eclipsed 2006 with a stunning 77%!

Forty-one percent performed at the Advanced level; 36% came in as Proficient. Seventeen percent were rated Basic, 2% Below Basic, and 3% Far Below Basic. (Due to rounding, this does not add to 100%.)

I'll update this post with graphics and more analysis eventually. For now, I'm going to enjoy the buzz.

And congratulate Rio Phyz 2013 as our best physics students ever!

Click here to see if this takes you to schoolwide results.

UPDATE: As promised, here is a breakdown and some longitudinal context for the 2013 data.

We begin with the most detailed breakdown: the number of students at each performance level. Performance levels are Advanced, Proficient, Basic, Below Basic, and Far Below Basic.

Rio Americano/Baird Student Performance, 2008-2013






This analysis leaves something to be desired. There's too much data to see larger, more important trends. A more telling chart compares "good" to "bad". That is, the numbers of proficient (or better) students to the number of basic (or below) students. This chart captures the relative proportions and the overall sample sizes from year to year, and is therefor the most useful chart for analysis.

Boiling it down too far yields a simple "horse race" result: what percent of the school's test-takers were either advanced or proficient. You lose sample size data here, so things can be somewhat misleading.

If this chart makes it appear as if 2012 in an anomaly, that's because it was. Rio did not have AP Physics in 2012. We will not have it in 2014, either. But EOC CSTs appear to have run their course, so no worries.

Rio's Physics CST proficiency rate of 77% stands as the highest mark among all the EOC tests. No other CST administered at the school had better results.

Districtwide, our 77% rate places us third among our nine comprehensive high schools. My hat is (again) doffed to Bella Vista and Mira Loma for their physics awesomeness.

Can too much emphasis be placed on the proficiency rate? Absolutely. An arguably better metric is the proficiency number: how many students scored as proficient or better. Rio's biology proficiency rate is always at or near the top for the school. While the physics rate of 77% is better the biology rate of 63%,  biology's proficiency number (63% of 521, which is 328) far outshadows physics' proficiency number (77% of 87, which is 67).

Still though, as a school, we end the Physics CST era on the highest note we've ever played.
