Serious Problem With New Student Assignment Plan
Please see http://www.cybermato.com/projects/school-assignments/new-sap-problem.html
for my comments on what I see as a very serious problem with the new Student
Is This Up-To-Date?
Apparently this still somewhat applies to the 2010-2011 school year
assignments. For up-to-date information, please see Elizabeth
A. Walkup's page on How to Rank Schools for the Seattle Public Schools at http://www.teriyakidonut.com/schools/choice-2010-2011.html.
The following information was originally written in February 2007, for
the 2007-2008 school year; however, it applies to the 2008-2009 and 2009-2010 school
assignments as well. Seattle
Schools is planning a new assignment process for
2010-2011 and beyond, but the current
assignment process is still in place for now through at least
the end of the 2010 school year. You should look at their enrollment page if you haven't already.
Is This Just For Kindergarten?
My focus in this process was on Kindergarten assignments, since I had a
son starting Kindergarten in 2007. However, the same system
applies to grades K-12, so the information should apply to everyone.
What About Private Schools?
Sorry, this page only applies to Seattle
Public Schools. However, I will say that if you're
interested in a private school for your Kindergarten-age kid, I am
thoroughly convinced that
Cooperative School is absolutely the very best school ever!
Why Did You Bother Writing This? Everyone Knows How
Everyone knows, but a lot of them are wrong, unfortunately.
As my wife & I navigated the process of choosing a
kindergarten (and school) for our son, we became concerned when we kept
getting conflicting information about the implications of listing
various choices on the school selection form. Even high-level
(principals and vice-principals) of the Seattle Public Schools were
giving out conflicting information, and obviously they couldn't all be
right if they were saying different things.
Some folks will tell you that you should never list a "long shot" (a
school you don't think you'll get into) as your first choice - they
call it "throwing away your first choice", implying that there is a
special magic about that first slot on the form. (It turns out this is
not true.) Others (not many) will tell you it doesn't matter.
Some people have told me some really crazy things that I
won't even record here. The basic problem is that it's a
system designed to be fair, first and foremost. It does a
good job of that, in my opinion. Unfortunately, it's not
possible for it to be both fair and simple, so it is a complicated fair
system, and the descriptions of it provided by the Seattle Public
Schools are accurate, but don't clearly lay out the important implications of how
Since we had some
very definite opinions about which schools would work best, we wanted
to do all we could to get him into those schools. So...
What Did You Do? Why Are You So Sure You Know
Better Than My Principal/Friend/Neighbor/Whatever?
Although the Enrollment Guide seemed fairly
clear, there were still a
couple of possible interpretations, and there was all that conflicting
information, and so in the end it became clear that there was one final
solution: read the source
code for the computer software program that actually
processes the applications and makes the assignments, creates the wait
No matter what anyone says, in the end, the software itself
is absolutely the most authoritative possible description of how the
process works, because the software is what actually does it.
So in mid-February 2007, after about 3 weeks
of negotiations with Seattle Schools to arrange it, I went down to the
school district office and spent several hours going through the actual
software which does the assignments. Apparently I'm the first
person who has ever asked to do that. I greatly appreciate
assistance of Joy Stevens in making this happen, and also Fred L. for
his time and effort in support of it.
So What's The "REAL Truth"?
I then spent several more hours reviewing my notes (I was only allowed
to take written notes - no electronic media of any kind was permitted).
I've now completed my analysis, and I will state the
following with conviction, with my reputation as a professional
software engineer on the line:
I did not pay any special attention to what would happen with twins.
My expectation was that the sibling-link provision would
typically ensure that once one of them was assigned to a school, then
the other would most likely be assigned to the same school, unless the
first one got the last spot at that school. However, I know
personally a family who wound up with twins assigned to two different
schools for 2007-2008, and who found Seattle Schools very uninterested
in sorting out the problem. I have a couple of theories about
what might have happened, but I'd need to have another look at the
source code to confirm them.
- The description of the process starting in the third column
on p. 36 of the 2008-2009 Enrollment Guide is accurate and
relatively unambiguous, at least if you're used to thinking like a
programmer. I strongly recommend that you read the guide and
try to understand it - it covers a lot of important information, almost
none of which I cover here. This page is all about one
particular issue, and there is much more to the process.
Unfortunately, while the Enrollment Guide is accurate, it
fails to call out some implications, which follow:
- There is no
harm in listing long-shot schools. I can't emphasize that
enough, because a lot of people (including some misinformed school
district employees) will tell you exactly the opposite. But
you list 6 schools that you have a less than 1% chance of getting into,
and then school X, you have no less of a chance of getting into school
X than if you listed school X first (unless of course you get into one
of the long shots, which presumably would be what you want).
your child) could get into your 7th-choice school, bumping out someone
who listed it as their first choice - this is pretty much guaranteed to
happen, if you don't get into your 1st through 6th choices AND the
tiebreakers (reference area, distance, lottery #, etc.) favor your kid
over that other kid.
- There is NO
SUCH THING as "throwing away your first choice". See # 2,
above - this is another way of stating the same thing.
- Listing a
school first (or second or whatever) does NOT give you any more of a
chance of getting into that school than someone who lists
it, say, 10th. See # 2 - this is another way of putting it.
- Figuring out which school to select to be wait-listed for
is trickier, because you can only pick one, but you (sort of) want to
pick the one that you think you have the best chance of having a short
enough wait list that you will actually get in. I don't have
good advice on this one. Sorry!
- It does not
matter when you get your form in - as long as
it's before the deadline (February 29, 2008)! The order in which the forms are
processed does not matter. The kids are assigned a random
"lottery" number for each school they listed. If kid C is
processed after kid B, but C (per the various criteria, siblings,
cluster, distance, and if all else fails, lottery number) has a higher
priority for a school to which B is already assigned, then B will get
"bumped" out and C gets into that school. Then, if that
happens, kid B gets processed again, starting with the next school on
their application, and may in turn bump out an kid A who is already
assigned to that school, etc. Allowing for that "bumping"
process ensures that the order doesn't matter, because this way even if
your application happens to be the very first one fed into the computer
and the very first one that it looks at when doing the assignments, you
could still wind up with your last choice (or not even that one), if
other kids have higher priority per the specified criteria.
It's a well-designed, fair system. Note that forms received after the deadline are processed separately, and
basically only have a shot at whatever slots are left after all the
forms received before the deadline are processed and all those kids are
assigned to schools. So don't be late!
Ugh, That's Still Too Long And Complicated - Give Me The
- If you are
interested in a "long-shot" school, list it!
Even first! It
won't hurt you!!
- The first
slot on the form is
- There is no such thing as
"throwing away your first choice"!
- List as many schools are you are interested in!
