About this rating

The red lines show The Times’ value-added estimates for this teacher. Yurkovetsky falls within the “most effective” category of district teachers in math and within the “most effective” category in English. These ratings were calculated based on test scores from 142 students.

Because this is a statistical measure, each score has a degree of uncertainty. The shading represents the range of values within which Yurkovetsky’s actual effectiveness score is most likely to fall. The score is most likely to be in the center of the shaded area, near the red line, and less likely in the lightly shaded area. Teachers with ratings based on a small number of student test scores will a have wider shaded range.

The beige area shows how the district's 11,500 elementary school teachers are distributed across the categories.

Isabella Yurkovetsky's Response:

On one hand I am happy to be rated most effective, on the other hand having taken statistics, I recognize that 35% margin of error renders this data at best inconclusive, at most invalid. LA Times has been a pioneer in backlash against public school teachers, an example of biased journalism & a champion of charter schools which skim our most promising students with promises based on falsified data. I challenge any reader who denigrates the efforts of teachers to come into my school and teach for one day. As to those who cry against the large proportion of immigrant children in LAUSD schools, where were your parents, grandparents, great-grandparents born? Blame the society that does not respect learning & is proud of its ignorance (Sarah Palin for President is one example), for the ills of the education system not the teachers. The witch hunt perpetrated by LA Times is driving many great teachers away.
