| Summary: | The objective of this report is to
describe the process and summarize the results from the
pilot implementation of statistical models for measuring the
value-added of Bulgarian schools through analysis of the
national student’ assessments results. This report presents
the technical aspects of the pilot and the key outcomes in
terms of value-added measure for each of the schools
included in the analysis. The report documents all data
processing, adjustments, and procedures run as part of the
school value added modeling and in this respect, it is also
intended expert statisticians and researchers. The national
student assessment results in Bulgaria are reported on a
non-transformed raw point scale accompanied by a table that
allows a transformation of the raw points to the six-grade
rating scale, adopted for measuring students’ performance.
Based on this, each school receives an average score and
some means of comparison with other schools in the country.
Analyzing the test results through value-added analysis is a
new approach for the country and the findings from this
pilot are intended to inform policy makers in Bulgaria about
the advantages and limitations of value-added measures
(VAMs) in the context of the Bulgarian education system, its
student assessment framework, and the data collected and
used by the education management information system. |
