Town of Needham Background Material
Numbers Can Be Deceiving
As we consider the candidates and ballot questions to be voted upon
April 10, we would do well to consider the fundamental issues at stake
rather than selectively quoting statistics to buttress various
viewpoints. If numbers are to be used, they should be used in context,
with the full knowledge that other perfectly valid numbers may in fact
call into doubt the numbers being cited. Let's step through some of the
letters to the Needham Times
in its March 15, 2007 issue for an illustration of this.... At
this point in time, I'm not personally sure how I'm going to vote on
the ballot questions. But I'm troubled by people using numbers
incorrectly when trying to influence me. While this is being done
by both proponents and opponents, numerically the proponents seem to be
doing more of this selective quoting of statistics. But this in
turn may just be because more letters in favor of than letters opposing
the ballot questions have appeared.
State Aid for Schools
One correspondent writes of a $1 million decrease in state aid to
schools in 2003. This decrease is genuine. What the correspondent
fails to mention is that state aid to Needham schools went up by a
factor of 2.9
between 1995 and 2007. State aid was $1.516 million in 1995 versus
$4.366 million in 2007. Is it
bad that there was a $1 million decrease in 2003? Yes. Is it good that
Needham now gets nearly 3 times what it did in 1995 in school aid from
the state, irrespective of the 2003 dip? Yes. Does either number help
you determine whether the Needham schools need additional funds?
Individually, maybe. Taken together, probably not. It turns out you
can
"prove" state aid has multiplied or stayed flat depending upon whether
you choose a 5 or 10
year horizon for your "proof."
Rising School Costs
The same correspondent writes of various costs to the Schools rising
substantially. Among the costs cited are transportation and health
care. The driving
factor in the School budget, however, is salaries, which represent,
according to
the Superintendent's budget, 86.7% of the School budget.
By way of contrast, transportation is 2.6% of the budget and Health Services are 1.6% of
the budget. Health care costs could therefore double from next year's value from 1.6% to 3.2% and still cost
the Schools about the same as a "mere" 3% increase in salaries. How, then,
can the Needham School Committee be proud of keeping
this year's salary increase around 3% (which isn't really correct,
either,
depending on how you do the math), while at the same time using the
doubling of
relatively small dollar value line items to justify a need for a larger
budget? In fact, the two numbers being used, one to show prudence, the
other to show spiraling costs, come out to about the same dollar value.
Needham's Spending on Education Relative to Other Towns
Another letter suggests that Needham uses its school funds
efficiently, citing specific amounts from the School Performance
Report. If you wish to vote on
this basis, however, you would be wise to visit the MA Dept of
Education's web sites at http://profiles.doe.mass.edu and
http://finance1.doe.mass.edu/statistics, which have full educational
statistics for all towns in the Commonwealth. The DoE web sites
allow
a voter concerned about Needham's relative educational spending to
view a range of spending statistics compiled by the state for all
towns, not just towns selected for comparison by the author of the
School Performance Report. The DoE
notes that the numbers, even on
different parts of its own web site, may not match up, which is the
very problem I'm trying to point out -- you can "prove" whatever you
want if you find the right numbers.
Cost of High Rock Renovations
Then there is the cost of the High Rock renovations. A correspondent
March 15 used values from a May 2006 draft of the Facilities Master
Plan rather than from the final report in November 2006. The final
report lists 6 "top rated" school options ranging from $14.4 million to
$84.6 million, whereas the correspondent cites a top number of $62.2
million. The "High Rock" option, at $14.4 million, is rated as
"minimum" on page 3-2 of the report with no positive attributes. Given
that the cost on the ballot for High Rock, only 4
months after the Master Plan was complete, is over 40% higher than it was in the
Facilities Plan, what
does this mean for our Town's future building plans? And why is the School Committee advocating for the
"minimum" plan instead of some plan with more educational advantages?
Class Sizes
Another letter references class size. Those who advocate for smaller
class sizes fail to mention that the official School Committee policy
states that a Grade 1-5 class in Needham can have up to 26 students,
and up to 29 students with an aide. If the writers believe in smaller
class sizes, they might wish to take up this matter with the School
Committee rather than appealing to the voters. The Schools' voted
budget and
suggested reductions if the operating override should fail all, to my
knowledge, keep class sizes within the School Committee's policy.
Tax Increases Lead to Doubling Taxes
Finally, there is a correspondent who suggests that tax increases at
the present rate will double property taxes in the next decade. While
this is true mathematically, it takes the High Rock tax increase out of context.
Tax increases voted on as part of continuing operations -- for example
the operating override for the Schools this year -- would, in fact, end
up doubling property taxes if a similar increase were to be voted every
year for a decade. This "if" strikes me as pretty unlikely in real life, regardless
of its mathematical accuracy. Debt exclusion overrides to complete
capital projects such as the Library or High Rock do not, however,
multiply -- they are only in existence for the life of the bonds
necessary to fund the given project.
Summary
Hopefully, the material above suggests that the numbers being cited by
various parties on either side of the 2007 ballot questions may not be
all
that they seem. No doubt these parties who wrote the letters will
be delighted to suggest that any numbers I have introduced above are
"misleading." This would be ironic, since the intent of this note is
to suggest exactly that -- that any number can be misleading when taken
out of context, and that rather than relying on selective quotation of
statistics to advocate for a course of action, that we as a Town debate
the more fundamental underlying questions that lie before us.
Fundamental Issues
Having suggested that perhaps the fundamental issues aren't being
discussed, what might I personally think some of these issues are?
- State Aid for Schools
- When State Aid decreases, to what extent should the Town's
taxpayers "pick up" the decrease? In what year after the
decrease? If there is a corresponding increase in state aid,
should school spending be restrained from using the increase to provide a
reduction in the tax burden that presumably would help to offset the
increase in the tax burden had local taxpayers "picked up" previous decreases in
state aid?
- Rising School Costs
- School salaries are rising at a higher annual rate than the Town's annual revenue increases. What should we do?
- Are teachers being overpaid?
- Is it possible to pay teachers and other school staff a fair
wage living in eastern Massachusetts under Proposition 2 1/2?
- How should the School Committee approach this year's contract negotiations?
- Needham's Relative Spending on Education versus Other Towns
- Why should we even care? We should be providing quality
education, not trying to spend the same as someone else. There
are cases where education dollars are stretched to provide good
educations in school systems with low budgets, and cases where school
systems, even when showered with money from philanthropists, still fail
to perform with extremely high per-pupil spending. There is a
body of inconclusive research about whether the money spent per pupil,
or household income of pupils, or education level of pupils' parents,
or various other factors are the most important guide to a child's
performance from a statistical point of view. Relative spending
can be used as a sort of sanity check to make sure you're not way out
of line, but it seems like a dubious argument for spending more or less
money. To counter my own statement, it turns out that several
years ago Needham was spending way more per SPED (Special Education)
pupil than any of the surrounding towns the School Department chooses
to benchmark against. Successful efforts have been made to
address this and bring Needham's SPED spending in line with our
neighbors. This is an example of how one might use relative
spending figures legitimately.
- Cost of High Rock
- If there is a middle school overcrowding problem, why is the Town proposing to build an elementary school at High Rock?
- This will be the 3rd elementary school, plus the high
school, to have been built while middle school overcrowding was a known
problem.
- Is the High Rock renovation a standalone $21 million project
with Pollard wiring improvements, or is it a "free" elementary school
with the real intent being to propose a $35+ million dollar middle
school at DeFazio in 2013 because the proposed 6th grade center is an
interim solution?
- Is it fair to the voters to ask them to build a building for
$20 million that will cost more than $20 million to operate? That
is, the real cost is double what is being proposed. The Selectmen
and School Committee don't want to "confuse" voters with this fact.
The preferred solution is to gain approval to construct a $20
million building and then, once construction is underway or nearly
complete, ask the voters for the $1+ million per year needed to
actually open the building.
- What is the plan for addressing middle school overcrowding if the High Rock article does not pass?
- (For potential answers to some of these questions, see the
Finance Committee's opinion at Fall 2006 Special Town Meeting on the
High Rock Design article, and the Finance Committee's comments to the
School Committee on February 27 and the Selectmen on March 6 on High
Rock operating costs. The High Rock questions above have actually been
discussed at some length, although some remain unanswered.)
- Tax Increases
- There's an interesting supposition on many peoples' part that
taxes will only go up 2 1/2% a year because of Prop 2 1/2. But
that's not correct for Needham, at least in the recent past or the
foreseeable future. Past votes on overrides affect present and future
taxes. Why aren't the already voted tax increases that have yet
to be levied better documented for voters as they consider yet
additional increases layered on top of the existing ones?
YesForNeedham Slide Show
The group "Yes For Needham" has a fascinating slide slow here
as of March 27, 2007. I think it may be the source of data for a
number of the correspondents using selectively quoted statistics.
Again, simply because the slides have so many heavy-handed
statistical issues does not mean that the operational override is bad
or good, but I really wish that people would present issues with a bit
better balance, although in this case where we have a political
advocacy group registered with the state Office of Campaign Finance,
perhaps balance is not to be expected.
People Move Here for the Schools
...and they get a good deal. This is the premise of slides 2-3.
While I haven't looked up the actual valuation statistic, at
least in my family's case, we moved here because the schools were good and
the real estate was less expensive than Westwood, Belmont, Wellesley,
Dover, or Weston, "comparable" school districts cited on slide 3.
It's not clear what these slides are trying to show -- see the comment
above on Needham's spending relative to other towns. Is it the
intent of the slide that Needham's taxes should be in line with
Weston's or Dover's? Are the authors unaware of the different mix
of housing stocks, commercial and residential property, and other
differences between the towns cited? Slides 4-5 go on to point out that
the average Needham tax bill is about $3,300 less than the per-pupil
educational cost of the schools. It's not clear what the intent
of this slide pair is, either. Is the suggestion that, for
example, it's OK for Needham taxes to rise by $3,300 per household?
If we want to get real comparison numbers, the state calculates a
"foundation budget" for each municipality in MA that represents "an
adequate spending level for a school district" that "constitutes an
adequate-but not excessive-level of funding." Many more details
can be found here
at the state Dept. of Education web site. The current foundation
budget for Needham is $7,787 per pupil -- if the town is already
spending $9,285 per pupil, why is our present spending inadequate?
Are the state's numbers that far off? Well, the foundation
numbers are skewed toward larger cities with more ELL and low-income
families -- those municipalities have higher foundation budgets than
Needham. So Needham has to spend more locally to "keep up."
Maybe $9,285 is fair. But the numbers aren't nearly as clear-cut as some would have you think.
Teacher Contracts
This is on slide 6, and is one of the big annoyances of this budget
year. Again and again, we hear that, to quote the slide, "Fixed
costs of teacher contracts...must be paid by law." This
justification has been hauled out in the past, but it happens that this
year in Needham the teacher contract is up for renewal. There is
an element of the teacher contract that must be paid by law because the
School Committee, in the last contract, included a 1% "kicker" raise
for the teachers on the last day of their contract, but
the salary figures in the school budget for this coming year do not
necessarily have to be paid by law, nor are they a fixed cost. In
fact, the terms have not even been negotiated yet with the teachers'
union. How anyone can declare an unnegotiated contract to be a
legally required fixed cost is not clear.
A 7.4% Increase is "Lean"
Slide 10 is full of interesting statements. We have the
unnegotiated teacher contract being cited as a legally required
payment. We have the SPED tuition contingency being cited as a reason
for budget increases -- there has historically been a SPED tuition
contingency in the school budget, this is not some new concept. Then we
have the teachers for the new children entering the system. As
noted a few slides farther on, these teachers cost $150,000 or
so. It's actually the unnegotiated salary increases and the
restorations that make up most of the budget increase, not these 3 new
teachers. Slide 11, however, keeps on hammering home that the
unnegotiated teacher contract is a "legally required payment." Hmmmm....
The Science Center Shuffle
Slide 12 talks about the restorations as if they're part of the
override. But they aren't anymore, or some of them aren't.
The people who put the slide show together are apparently
confused about what's in and out of the base budget versus the override
this year, which is understandable because the School Committee changed
it around late in February. See here
for an attempted clarification (PDF, Acrobat required). Green
items are in the base budget and not subject to the override. So
we get elementary piano accompanists and part-time elementary
psychologists in the base budget, and cut classroom teachers instead.
The Science Center goes into the base budget, and we cut
classroom teachers instead. The "Yes For Needham" slides don't
clarify these late Februrary budget changes, and they probably should.
