The method is to relate
the level of PO with
the number of hours devoted
to the COs which address
the given PO. If
>40% of classroom sessions addressing a particular PO, it is considered that
PO is addressed at Level
3
If 25 to 40% of classroom sessions
addressing a particular PO, it is considered that the PO is addressed at Level 2 If
5 to 25% of classroom sessions addressing a particular PO, it is considered that the PO is addressed at Level 1
If < 5% of classroom sessions addressing a particular PO,
it is considered that the PO is considered notaddressed.
