+eliability Analysis: Table A is showing alpha’s (Cronbach’s Coefcient) estimated values to determine the consistency (internal) and reliability o measures. In sample under consideration cronbach’s alpha’s values range rom !."#$!.%& which represents that every construct (multi item) contains high reliability' .*.+. practices (, - ."%#) competence ( , - .%&') org. commitment (, - ."%) /ob satisaction ( , - ."#! ) motivation ( , - ."#& ) teachers perormance$in role ( , - .""! ) 0 teachers perormance$e1tra role ( , - .%!' ). The high value o cronbach’s , or every construct represents internal consistency o the constructs. In short higher the value o Cronbach’s alpha higher the reliability will be o the construct.

Samling ade7ua*y test0s 8M3 measure 9 Sheri*ity0s Bartlett0s test: The 6+7 measure tells suitability or e1ecuting actor$analysis. 6+7’s value ranges rom ! to '. A ! value represents larger dispersion in correlations pattern thereore employing actor analysis will become inappropriate. 8alue ' represents that the correlation patterns are relatively compact hence employing actor analysis will become appropriate. The rule o thumb or 6+7 value is that a !.2 value is poor value ranging between !.2$!.3 is mediocre value ranging between !.3$!." is good value ranging between !."$!.% is great 0 the value above point nine is superb according to utcheson 0 9oroniou ('%%%). The results in Table : suggest that 6+7’s value is above recommended degree o !.# or every construct with an e1ception or motivation i.e. (6+7 - !.2!!); *+ practices’s 6+7 - !."2' competence’s 6+7 - !.""4 org. commitment’s 6+7 - !."#3 /ob satisaction’s 6+7 - !.3&2 teachers perormance$in role’s 6+7 !."!" 0 teachers perormance$e1tra role’s 6+7 - !."##. The 6+7’s value or motivation alls under mediocre category as per utcheson and 9oroniou hence is acceptable. This represents that in case o given data actor analysis is worthy to be conducted.
To test relationship signi5cance among all items o one construct :artlett’s test is conducted.
!.!2 is con5rming relationship signi5cance between variables under consideration. Table : is indicating that the signi5cance o :artlett’s test came below !.!!' or all constructs giving evidence or null hypothesis or no $ correlation. Thereore we can perorm actor $ analysis.
