Many open questions in state’s “Growth for All” accountability plan
Not only is New York State proposing a “proficiency plus” accountability model that will take both absolute proficiency and student growth towards proficiency on state reading and math tests into consideration, it is also looking at creating a “growth for all” system to reward schools who move already proficient students to even higher levels of proficiency, and, perhaps, penalize schools where proficient students do not make additional gains. This part of the accountability system would not require federal approval, presenters stressed at last week’s public forum on the model.
According to the presentation by Ira Schwartz of the state education department, many ideas are still on the table for where to set the bar for growth, how to compare students and schools, and what positive or negative incentives schools could expect under the new system.
First, the state must determine what schools should strive for in educating students who already test proficient. Is it enough that students continue to test above the proficiency cutoff, or must they show one year’s growth or more when scale scores are compared? The question echoes this summer’s debate over whether to emphasize the “proficiency gap” or the “achievement gap” in looking at student performance.
Asked whether some parents and educators might choose to improve the teaching of non-tested subjects such as art, music, and physical education rather than devoting more resources to helping proficient students score even higher, Schwartz responded that the Regents had specifically asked for a way to hold schools accountable for the growth of all students.
Next, the state must decide how to compare schools. New York City’s Progress Reports got a nod for their peer group comparison, (more…)

State’s accountability proposal projects growth towards proficiency
In October, New York State is submitting a growth model proposal to the U.S. Department of Education, I learned at last week’s public forum on the proposal. What would school and district accountability look like under the new model?
For grades 3-8, schools would earn points towards meeting Annual Yearly Progress (AYP) for each student scoring proficient or above (a level 3 or 4 on state tests), but would also earn full points for level 1 and 2 students whose growth indicates that they are on track to become proficient within a four-year period.

A simplified example of how the growth model would determine whether a student is on-track to proficiency.
The graph above provides an oversimplified example. The blue line represents the cutoff score for proficiency at each grade level. Bill and Ted each start out 100 points below proficient. In 4th grade, Bill has gained enough that he is now only 70 points below proficient. As you can see by the red line, if he continued to grow at this rate, he would reach proficiency easily by 7th grade. Therefore, Bill is deemed to be on-track to proficiency, and his school would get full credit towards Annual Yearly Progress for him.
Ted, on the other hand, is still 95 points below proficient in 4th grade. He made more than a year’s growth, but if he continues to grow at this rate, he will not reach proficiency by 7th grade. Ted’s school would not get full-credit towards AYP for him.
Of course, in real life, students don’t grow at exactly the same rate every year. (more…)

State proposes “proficiency plus” accountability model
Dozens of educators, policymakers, and advocates gathered at United Federation of Teachers headquarters this morning for the first in a series of public forums to discuss proposed changes to New York State’s No Child Left Behind (NCLB) accountability system. The Board of Regents is seeking feedback on a new growth model, which is designed to provide “differentiated accountability” for schools, before they submit it for approval by the federal department of education in mid-October.
Ira Schwartz of the New York State Education Department presented the proposal, stressing that a growth model allows the state to more carefully assess the work of schools by looking both at the number of students meeting absolute proficiency standards and the rate of growth of students who have not yet reached proficiency.

By combining these measures, he said, the state could differentiate between schools with low absolute scores where students made significant growth, and schools with both low scores and low growth. The same distinction could be made for schools with high absolute scores, separating schools that continued to push students to higher levels from those where individual students do not make much progress.
The state hopes to use a growth model both to “make more refined… decisions” about whether schools have made Annual Yearly Progress (AYP), and to go beyond AYP to measure the growth of students who have already reached proficiency. Schwartz noted that while the use of a growth model for determining AYP status must be approved by the U.S. Department of Education, the second part of the proposal, going beyond NCLB to look at the growth of proficient students, does not require federal approval.
Schwartz’s presentation mentioned New York City’s Progress Reports as an example of a locally-developed initiative that takes student growth into account, which sparked criticism by some educators in the room. “I hope they’re not using New York City as a model of success for this,” one principal said during the question-and-answer period.
And Leo Casey, who spoke for the United Federation of Teachers (UFT), emphasized that any accountability model must be fair and complete, accurate, and transparent — no “statistical hieroglyphs,” in order to be meaningful to teachers and families. “If grades and accountability careen all over the place, from F to A and A to F, educators will experience them like the weather,” he said. Casey concluded that although there are still areas needing work, the state’s proposal is an improvement over the current system.
Upcoming posts will detail the state’s proposals for elementary and middle schools, high schools, and for measuring the growth of already proficient students.
