Assessment of Sport Skills and
Motor Abilities
Guidelines for Sport Skills Testing andMotor Performance Tests
• acceptable reliability and validity• simple to administer and take• easy to understand instructions• not expensive nor require extensive equipment• reasonable time for preparation and
administration• encourage correct form• involve only one participant
Guidelines for Sport Skills Testing andMotor Performance Tests (con’t.)
• suitable difficulty• interesting and meaningful• exclude extraneous variables• provide for accurate scoring• provide target scoring guidelines (if appropriate)• sufficient trials• yield diagnostic scores
Effective Testing Procedures
• Pretest Dutiestime, forms, procedures, instructions
• Testing Dutieslocation, materials, cheating, safety,absences, make-ups
• Posttest Dutiestranscription, item analysis, reporting,confidentiality

Issues in Skills Testing
• In addition to reliability and validity(the most important issues)
• Feasibility
• Testing methodObjective skills tests?Alternative (authentic assessment)? – See
chapter 8
Skills Test Classification
• ObjectiveAccuracy-basedRepetitive Performance (wall-volley)Total Body MovementDistance or Power
Subjective Rating Scales
• Relative Rank-order
• AbsoluteEvaluation against a
fixed standard
• Common ErrorsHalo Effect"Standard" ErrorCentral-tendency
Developing Well-Constructed Scales
• State objectives in terms of observable behavior• Select traits that determine success• Define selected traits in observable behavior• Select and develop the rating instrument• Define degrees of success• Test and revise the rating scale• Use the scale in an actual testing situation
More Rating Scales Suggestions
• Develop well-constructed scales• Train raters well• Explain common rating errors to raters• Permit ample time to observe performance• If possible, use multiple raters
Other Tests
• Performance-Based TestingActual performance of the skill
• Trials-to-Criterion TestingCould save considerable time and effort
Ability or Skill?
• Abilitygeneral, innate psychomotor trait
• Skillspecific, learned psychomotor capacity
• Specificitydetermined with concurrent validity

Effective testing consists of . . .
• Including sport relevant variables,• Selecting reliable and valid tests,• Developing sport specific protocols,• Controlling test administration,• Maintaining athletes rights to respect,• Repeating the tests periodically, and• Interpreting the results for the performance and
interested parties (e.g., coaches, parents, etc.)
