As the mayoral-control debate escalates hereand in Albany, a parallel conversation is simmering locally, about the city's recent rise in standardized test scores.

Two Daily News articles set a strong counterpoint: Last week, columnist Juan Gonzalez challenged the gains touted by the Department of Education, asserting that poor children lack the opportunity for achievement that many others have -- and that charters, which enroll far fewer English language learners and special-needs students, benefit from their exclusionary policies. Gonzales concludes, "...when something looks too good to be true, it usually is. "

Today, big jumps in reading scores are celebrated in the News -- but a principal's explanation of how her school improvedtest scores is chillingly revealing: "What really helped us was looking at our data and driving the instruction based on that," Principal Lillian Catalano, a 23-year public school veteran, told the News. School officials "spent hours scouring" students' work on previous assessments to figure out "where they needed help ... on the statewide reading test," the article explains.

Simply put, this principal and her faculty embraced the data -- and upped their scores by 'teaching to the test.' They figured out what kids needed to know to do better, and they taught it. But teaching to the test necessarily takes time from other subjects; it limits what a school can offer, and what a teacher can teach. And it doesn't mean kids are actually learning to think for themselves or master content outside the testing area. Historically, teaching to the test was universally considered a bad thing, but tables turn, and today, it's lauded. Schools that do the best job of sussing out what the testers want gain the most praise and public recognition; progress reports, based largely on a school's test scores, can determine a principal's tenure and even a school's survival.

It's hard to argue with a principal who sees the importance of raising scores. The bigger question is what's lost when the focus-field narrows -- when data, scores, and testing outpace content in the classroom.
