This paper will develop an insight into the role of a teacher to identify the children with Specific Learning
Difficulties (SLD) among the students in mainstream classrooms. It will enhance the quality of teacher education
of the teachers working in the regular classrooms without knowing the specific learning difficulties of the
students through the valid instruments and procedures. The presentation will discuss the report on the Validation
of Sequential Problem Test (SPT) for identification of children with Specific Learning Difficulties from regular
school classroom with purposive sampling techniques. The test was validated by the advance statistical measures.
IQ and classroom achievements in Urdu were adopted to determine criterion & discriminant validities as
procedures. For stability reliability, test retest reliability was used. Internal consistency was determined through
Scale of Reliability Cronbach’s alpha coefficient. Item Characteristics Curve (ICC) by score for each item of the
tests with zero and one response was drawn for item fitness.
