Changes in Data from Year to Year    • The federal government
required changes in how each state counts highly qualified
teachers this year. In 2004-05, an elementary teacher was
counted once for all classes taught. In 2005-06, each of the 5
or so classes taught by each elementary teacher counted
separately.    • To the extent that elementary teachers are
often more highly qualified, that additional weighting this year
could affect some overall district totals.    • Therefore, the
best comparison is within subjects (English, math, etc.) and
within categories (elementary, middle/high school), where there
was NO relative change in the federal rules for counting highly
qualified teachers.
