The tables in this report on professional salaries were prepared using data submitted by Maryland's 24 public school systems in the fall of 1997. Salaries include annual pay for 10-, 11-, and 12-month employees in positions listed. All data reflect the conversion of part-time employees to a full-time equivalent. The position types used in the report are based on definitions included in the Instructional for the Annual Staff Reporting, Maryland Public Schools, April 1997. Directors, coordinators, and supervisors include persons in charge of instructional and noninstructional services within the school system. A figure provides data on amount above/below statewide average teacher salary. Three tables provide data on salaries of professional staff employed in Maryland public schools, teachers' salaries indexed to region, and average salaries for selected positions and 10-year percent change. Highlights of the report include: (1) the average salary for principals increased about 3 percent from 1996-1997 to 1997-1998; (2) compared to the 1996-1997 results, the mean on statewide teacher's salary is slightly higher in 1997-1998; (3) the average teacher salary increased in four geographical regions of Maryland (western, southern, lower shore, and upper shore); and (4) pupil personnel/school social workers showed the biggest gain in average salary.
