The careers of 799 male and 1,265 female teachers employed in Oregon school districts were traced for 4 years from 1962 to 1966 to determine the teachers' survival rates. The primary method of analysis chosen was an actuarial approach which involves construction of a survival curve showing numbers of teachers surviving after each period of time and the rapidity with which the initial group of teachers leave their districts. Results show that nearly seven out of 10 teachers hired by Oregon school districts will no longer be serving as classroom teachers in the same districts 5 years later. The shortest survival expectancies were found among females between the ages of 20 and 24, next shortest amount females between 25 and 29, and males between 20 and 24 were the third poorest risks. Over 40 percent of all newly appointed teachers were in these groups. On the other hand, ladies in the 40 to 54 age group had the best survival records, but barely 10 percent of newly employed teachers fell into this category. Administrators seem to employ just those teachers that have the poorest experience of surviving. Differences in survival rates for male teachers were observed among districts, with more populated districts having the best records and the remote, less populated ones the poorest. (TT)
