If this is the case, there is no achievement gap in math.

The state used to publish PARCC scores in five levels distributed by race. If you compare that distribution with this distribution, you will see that this is a heavily manipulated outcome.

Good points. One thing to keep in mind with the downcounty MS magnets is that from my experience very few kids from ‘W’ cluster schools elect to attend, at least I know this for Eastern. Maybe TPMS is different for Asian students who want to proceed to Blair? But in our case, coming out of CES, every parent from a ‘W’ cluster is except WJ would not consider the magnet or actually declined a seat when selected. Maybe you miss some computer science, but you still take AIM at your home school and MCPS has been increasing the number of “advanced” courses offered at home schools.

I don't think this parent actually has a student at Eastern because if you did you'd know the buses from BCC, Whitman and Churchill area are completely full and there are many kids going to Eastern not just TPMS and Blair. If you look at the directory, a very large number are Potomac or Bethesda addresses.

Because I apparently have infinite time on a Friday afternoon, here is the breakdown of the top 5 zip codes for every child in the directory:

20910 - 33
20910 - 19
20902 - 17
20854 - 14
20895 - 13

So, the first three zip codes are Silver Spring and Takoma Park. The next is Potomac and the last is Kensington. That's great, and I have a lot of admiration for the kids willing to ride the bus all the way from Potomac. But it's actually pretty balanced and certainly the numbers above *feel* true to me as a two-time Eastern magnet parent who knows other parents and whose kids hang out with other Eastern kids. A lot of them are thankfully right in the neighborhood.

Do you have data for this? I recall that 2 years ago we were looking at locally normed CogAT, not MAP tests. It is important to realize that the local norms didn't include the full MCPS population, just those who were identified and tested for admission. So yes, a 97th percentile nationally was lower in the local norming because the local norming population had already been pre-screened and already represented only the top half of the population. I do not recall any instances where 75th percentile nationally was 90th percentile locally, and I don't believe that is true; in fact, I don't remember any reports of a national percentile being dramatically lower than a local percentile, but maybe I'm forgetting.

I have a child who attended a high poverty school, so I saw the "local normed" cogat and the national cogat for the same raw score. They were the same. So unless someone comes out of the woodwork to say that there was a huge difference between the locally normed number for a rich school and the national percentile, then I don't think we can trust PP's narrative.

I think that's the point. That the achievement gap is real therefore there's no way it was a completely random unweighted lottery. There are other factors like the high rate of FARMS admissions that show it's mathematically not random.

But if these scores were locally norned the distribution would look very different so I'm not sure this tells us anything about their admissions.

Right. The whole point of that smart PP's post. That they must have done things like local norming, extra points for ever FARMS and other things so that it wasn't a straight random lottery of everyone in the pool weighted equally.

Not so sure it's all that good a point unless the state published PARCC data so that it could be locally normed otherwise it's just a very rough guess that tells us little.

The “good point” is that to have an outcome that results in a racial demographic that mirrors the county’s racial demographic for Black and Hispanic students would presume that those demographics were reflected as such in the lottery pool. Since the pool is the “top 15%” then the top 15% of student is highly racially balanced. That means that there is no achievement gap. Or it means that there is an achievement gap but MCPS put a thumb on the scale to ensure a racially balanced cohort. It cannot be both. If people want to keep saying “random lottery” then the implication is that there is no achievement gap.
