Performance AssessmentPerformance Assessment
Methods that enable children to demonstrate their knowledge, skills,
and personality through performing tasks that are part of their daily
experience.
The best way to evaluate a child’s performance is to study performance, not something else.
Curriculum-Embedded Assessments
Assessments based onstudents’ typical classroom
performance.
The Work Sampling SystemThe Work Sampling SystemA continuous progress, instructional assessment
that uses:• Guidelines and Checklists,• Portfolios, and• Summary Reports
To help teachers document and assess children’s skills, knowledge, behaviors, and academic achievements from preschool (3- year olds) to Grade 6.
Purpose of aPerformance-Based Checklist
Purpose of aPerformance-Based Checklist
• Observe and document children’s skills and accomplishments,
• Keep track of what individual children know and can do,
• Plan developmentally-appropriate classroom experiences throughout the year.

Purposes of Portfolio Collection
Purposes of Portfolio Collection
• Shows quality of work
• Demonstrates progress
• Displays work across domains
• Involves children in evaluating their work
• Assists with instructional planning
Summary ReportsSummary Reports
• Combine information from Checklists and Portfolios
• Rate student performance and progress
• Highlight strengths, concerns, and plans.
SUMMARY REPORTS: WSO offers templates and tools for creating Family Reports to share with families.
OUTCOMES REPORTS: WSO aggregates data. Reporting on each of the domains, components, and indicators available.

Purpose of Study
To evaluate the validity ofthe Work Sampling System (WSS)
as a measure of children’s learning and academic
achievement.
Principal Study Questions
• Is WSS a valid means of evaluating student achievement and progress?
• What is the impact of WSS on families?
• What is the impact of WSS on student learning?
Sample for the Validity Studies
• K – 3, cross-sectional
• N = 345
• 17 classrooms (volunteer), 5 schools
• 70% African-American, 80% free and reduced lunch, 49% male, 8% special needs
Results of the WSS Validity Study (K - 3)
• WSS correlates very well with a standardized, individually administered psychoeducational battery (the Woodcock Johnson-Revised);
• WSS is a reliable predictor of achievement ratings in kindergarten – Grade 3;
• Data obtained from WSS accurately discriminate between children who are and are not at risk.
Accuracy of WSSTeacher Ratings
When two students––one with reading difficulties and one without––are chosen randomly, the student in academic difficulty has an 84% chance of being ranked lower on the WSS Language and Literacy checklist than the student without reading problems.
Parental Reactions toWork Sampling
Parental Reactions toWork Sampling
• Hold positive attitudes toward WSS• Believe that WSS is beneficial• Prefer WSS summary reports to conventional
report cards• Want their children to continue participating in
WSS classrooms
Parents in this study (N = 246; 70% return rate):
How Parental Reactions Are Formed
How Parental Reactions Are Formed
• Parents’ perceptions of teachers’ willingness to use WSS.
• Teachers’ availability to answer parents’ questions about WSS.

Impact onAchievement Test Scores
WSS, low-income, urban, minority third and fourth grade students’ (N=96)
performance on the ITBS exceeds the scores of a matched contrast group
(N=116), and those of other students in the district (N=2922).
Conclusions• WSS is a valid and effective assessment of
children’s learning.
• Teachers and families are satisfied with the system and become more so as they have more experience with it.
• Students in WSS classrooms make significant achievement gains.
Benefits of an Observational Assessment System
Benefits of an Observational Assessment System
• Focuses on what children know and can do
• Engages teachers in the assessment process
• Demonstrates progress over time
• Adaptable for diverse students
• Understandable to parents
• Instructional in orientation; not high-stakes
