The percent of male teachers in various countries surveyed by TIMSS correlates with the Crosslinked TIMSS Scores.

The percent of first level and second level teachers who are men according to the UN Stastical Yearbook, 37th Issue, page 116, differs significantly from the TIMSS survey data for an as yet undetermined reason.  The UN data for the percent of first level teachers who are men correlates more closely with the Crosslinked TIMSS scores (r-squared = 0.4815) than it does to the percent of second level teachers who are men (r-squared = 0.1565), but both correlate significantly better than the TIMSS data (r-squared = 0.0002).

Examining the above charts for extraneous data points leads to the following conclusions:

1. Inconsistencies between TIMSS and UN data for both Singapore and Hong Kong requires the use of their own estimates.
2. Inconsistencies in data from previous Soviet countries requires data from Latvia, the Slovak Republic and the Czech Republic be omitted.
3. Iran, Iceland, and New Zealand are temporarily excluded from the correlation analysis so they can be examined more closely to determine why they fall so far outside of the model.
4. The R-squared of 0.7373 is expected to increase to close to 0.9 as other data points are verified.
