Specification grid 2077

 

     Grade: 11                                                                                                              Theory (Com. 427)

 

Remarks:

Item format in composite should be met as per the specification grid.

 

Designated weightage of the units/content areas should be met.

 

In the case of SAQ and LAQ, these should ensure that 1 mark will be assigned per element expected as correct response.

 

The distribution of cognitive domain of questions should be nearly 15% knowledge/remembering, 25% understanding, 30% applying and 30% higher ability level. Higher ability includes analyzing, evaluating and creating level.

 

SAQ and LAQ can be structured (have two or more sub-items). SAQ and LAQ can be distributed to two or more cognitive behaviors. In such case these will be added to their respective cognitive behavior. In sum the distribution of cognitive behavior should be approximately to the required distribution.

 

In case of SAQ there will be 2 "OR" questions and in case of LAQ there will be 1 "OR" question
