Well, it doesn't matter anymore.  In response to a FOIL request, NYSED sent me a database of over 270,000 teacher and administrator salaries, listed by district and employee name.  You can download it here.  A summary of the data appears below, in alphabetical order, followed by a table of county and regional averages.

The 50th percentile salary is the same as the median salary (not the average salary).  It is the salary earned by the teacher whose salary is exactly in the middle, between the lowest and highest salaries.  Teachers near the 50th percentile typically have 8 to 13 years of experience, but it really depends on the distribution of teacher experience and the number of steps on the salary schedule in each school district.

Count refers to the number of teachers in the school district.  Code is NY's district code.  The first 2 digits of the 6-digit district code equates to the county code.  "01" is Albany and the rest follow sequentially in alphabetical order.

College is the average number of years of college the teachers in the district have.  4 is equivalent to a Bachelors degree and 5 a Masters degree.  NY teachers are required to have Masters degrees, with exceptions for the first few years of teaching and for teachers grandfathered in after the change.

A_Exp is the average number of years of teaching experience of teachers in the district.

Avg_Sal is the average salary earned by teachers in the district.  The average is affected by the distribution of teachers on each step of the salary schedule.  A school district with a relatively inexperienced faculty will have a lower average salary than another school district with the identical salary schedule and more experienced faculty.

Top_Sal is the highest salary earned by a teacher in the district.  Sometimes this teacher may also have administrative duties.

ASP is the district's average salary percentile.  An ASP of 99 means that the district's average salary is higher than 98% of all other districts.
