INFORMATIONAL

TO: Division Superintendents
FROM: Paul D. Stapleton
Superintendent of Public Instruction
SUBJECT: SOL Tests -- Validity and Reliability
Enclosed is a copy of a report prepared by the Department 
of Education, Division of Assessment and Reporting, which 
provides information on the evaluation of the validity 
and reliability of the Standards of Learning Tests by 
three university-based testing experts, based on the 
spring 1998 administration. The Virginia Board of 
Education has shared this report with the General 
Assembly.  The report indicates that the SOL tests meet 
procedural validity criterion.  In addition, the second 
criterion for validity-correlation with other measures of 
student performance, such as the Literacy Passport Test and the
Stanford 9, has been met.  Test reliability  information based
on statistical analysis of the results  of the spring 1998 SOL
test administration confirms that  Virginia's SOL tests meet
accepted technical requirements  for reliability of scores.

Please share the information from this report with the 
schools in your region. If you have any questions, please 
contact Cameron Harris, Assistant Superintendent for 
Assessment and Reporting, 804-225-2102.
