# Charter Apologists Make Trumpian Claim Regarding “Hidden” Data Not Part of CA’s School Dashboard

**CHARTER WARS-**The [astroturf](https://en.wikipedia.org/wiki/Astroturfing) groups Parent Revolution and [SpeakUp](https://speakupparents.org/speakup-board-watch-take-action/2019/9/2/goldberg-attempts-to-abort-school-rating-system-deny-parents-access-to-student-growth-data) are flooding social [media](https://argonautnews.com/opinion-is-your-school-as-good-as-you-think/) of late with their PR-honed contention that opposing LAUSD [charter-advocacy-backed members](https://www.scpr.org/news/2017/05/18/71953/so-lausd-has-a-charter-backed-school-board-majorit/) Nick Melvoin’s and Kelly Gonez’ School Performance Framework (“SPF”), is “[hiding](https://speakupparents.org/speakup-board-watch-take-action/2019/10/17/usc-education-professor-calls-it-crazy-to-hide-student-growth-data-from-the-public)” data from parents.
 What sort of double-speak nonsense is it to claim that full access to direct data unencumbered by crazy data manipulation, is “hiding” data? Just publishing the data, as directed by board member Jackie Goldberg’s (photo left) alternate [resolution](https://boe.lausd.net/sites/default/files/11-05-19RegBdOBMaterialsWithLinksPublic.pdf), is the complete opposite of “hiding” it. “Hiding data” is in fact precisely what the [market-based Education-reform, charter-school ideologues](https://docs.google.com/document/d/e/2PACX-1vQ_I9aEgMe18yLBLgMKYoVEjaMFX1oH7KX2X7gdRYrtTd4pfEnsJd4RvxmOIucVoVXUVrSqH79bIU6u/pub) are *advancing* when they claim manipulated data is more true than the data itself.
This highly vaunted “growth data” they crusade for is a variant of the data manipulation enlisted by the same legions of “quants” arguing how best to maximize their personal stock portfolio. It is math (technically, algebra) weaponized for maximizing personal earnings. Not yours, not mine, and not students’ educational assets either. This is a neoliberal game for those who are [investing in education as a privatized asset](https://www.huffpost.com/entry/private-firms-eyeing-prof_n_1732856): financiers and charter school advocates.
What actually is “growth data”?
It is a tool of social science, comparing “apples to oranges” by employing a statistical technique to adjust for what is integrally different about the fruits, leaving a [debatably](http://www.carnegieknowledgenetwork.org/wp-content/uploads/2012/12/McCaffrey_CKN_Webinar_12-14-12.pdf) residual “direct” comparison.
The claim is made, for example, that if an apple tree were shaded and an orange tree grown in full sunlight, a better comparison of their “true” relative growth could be made by adjusting for sunlight and then comparing girth directly.
One of many difficulties with this calculation is that what you might really care about in the end is whether you prefer the taste of apple or orange. So even while taste and girth may be related, still girth is a poor surrogate for preference or “excellence” in this sense. Girth is just one of myriad contributors to the fruit’s excellence.
And adding more of these determinants only complicates the model with interactions and crippling levels of mathematical uncertainty – all without ever [reliably](https://www.esboces.org/cms/lib07/NY01914091/Centricity/Domain/330/ESBOCES%20Validity%20and%20Reliability%20June%202016.pdf) (or pragmatically) leveling differences inherent to the fruit.
But this is the SPF plan for comparing schools: to “handicap” (as for golfers) a school’s [contrived](http://parentsacrossamerica.org/wp-content/uploads/2015/01/RacialBiasFacts.pdf) [outcome measures](https://www.washingtonpost.com/news/answer-sheet/wp/2016/05/27/alice-in-parccland-does-validity-study-really-prove-the-common-core-test-is-valid/) through a host of adjusted variables intrinsic to some modeling formula no parent or member of the public ever sees, ever validates, or authorizes. We are asked to simply entrust consequential decisions to an opaque mathematical *prediction*. We are to rely on not the data itself, but someone else’s estimate of the future.
In other words, “growth” data is the very essence of data, hidden.
There is no shortcut around comprehending a waterfall’s worth of data beyond studying it. Collecting more of it may not necessarily improve prediction, and neither does rococo manipulation. California’s school [dashboard](https://www.caschooldashboard.org/) is a plain tool that presents just-the-data and offers a little [context](https://www.cde.ca.gov/ta/ac/cm/chronabscal.asp) for understanding. It does not transform data into something else. It is not pseudo-science distracting from alchemy. It does not erase or collapse complexity, which is fitting, because the right school for your child will mirror his own complexity.
Next Tuesday, November 5 the LAUSD school board will affirm our right to evaluate un-doctored data, plainly and truthfully. Raw data is effectively hidden when processed by ideological magic. It’s just a Trumpian humbug to pretend that only derivation can reveal the truth. We all deserve honesty. Tell your board member to support Jackie Goldberg’s resolution “Ensuring Support for Students.”
Find your schoolboard member through [this website](https://neighborhoodinfo.lacity.org/).
And convey your support for Tuesday’s “tab 25” ***today*** (on page 458 [here](https://boe.lausd.net/sites/default/files/11-05-19RegBdOBMaterialsWithLinksPublic.pdf)) directly as follows:
By phone: **213-241-*xxxx*** where Board District (BD)
BD1’s George McKenna is -6382 BD2’s Monica Garcia is -6180
BD3’s Scott Schmerelson is -8333 BD4’s Nick Melvoin is -6387
BD5’s Jackie Goldberg is -5555 BD6’s Kelly Gonez is -6388
BD7’s Richard Vladovic is -6385 Superintendent Austin Beutner is -7000
By email: according to the pattern ***first.last*@lausd.net**
