Preliminaries
• Course Outcome (CO)
• Course outcomes are statements that describe significant and essential learning that learners have achieved, and can reliably demonstrate at the end of a course or program.
• In other words, course outcomes identify what the learner will know and be able to do by the end of a course or program.
• Program Outcome (PO)
• Program Outcomes (POs) are narrower statements that describe what students are expected to know and be able to do by the time of graduation.

Preliminaries (contd.)
• CO-PO Mapping
• Each course outcome should be mapped to achieve the program outcomes
• At the beginning of each semester, module leader will set the CO-PO mapping and relationships between the assessment tools (e.g. Midterm, Semester
Final)
• The mapping should be mapped according to the level of correlation
• Low = 1, Moderate = 2 and High = 3
• Assessment Tools
• Only Midterm (25) and Semester Final (40) marks are considered for CO-PO Attainments.

Work Flow
ML will set the CO-PO Mapping
ML will set the Midterm &
Semester Final Questions
ML will circulate the CO-PO Excel to
the section teachers after
modifying according to the
question
Each Section Teacher will input
students’
information and question-wise marks & Send it
back to the ML
ML will calculate the CO-PO Attainments
ML will create Course File and Report for each
semester
Tasks of Module Leaders
• Inputs:
• Course Credentials (Semester & Year, Course Code, Course Title, level & term, Section, No. of Students, Module Leader (ML) Initial, Threshold (e.g. 50%)) in cell B7 to B14. (Fig. 1)
• List of students Student ID and Name, staring from cell A20 and B20 (Fig. 2)

Fig. 2
Tasks of Module Leaders (contd.)
• Inputs:
• CO-Question Matrix (Fig. 3)
• Input CO-wise marks in the marks in cell I9 to I13 and J9 to J13
• Number of Questions in Midterm and Semester Final
• In cell C17 to H17 (add or delete columns, if needed)
• CO Mapping for each question
• In cell C18 to H18 (add or delete columns, if needed)
• Assigned marks for each question (marked red Fig. 4)
• In cell C19 to H19 (add or delete columns, if needed)
Fig. 3
Tasks of Section Teachers
• Inputs:
• Each section teachers (including Module Leaders) will input student-wise question-wise marks

CO Attainment Calculation
• Put equation in CO-wise marks columns (e.g. CO1 marks (%), CO2 marks (%) etc.)
• For Example, CO1 is attained from Midterm (Q1 and Q2) and Final (Q1)
• Total marks for CO1 is calculated in CO-Question Matrix (see Fig. 3)
• CO1 Marks (%) = ( 3+𝑁+2
6+3+4 ) X 100% = 5
13 X 100% = 38%
• Therefore,
• CO1 marks (%) = SUM(C20,D20,J20)/K9
CO Attainment Calculation (contd.)

• Based on the percentage the CO1 Met(Y/N) column will be updated.
• If CO marks percentage is greater than or equal to the Threshold (cell B14), it will be “Y”, otherwise “N”
• CO1 Met (Y/N) = IF(Q20>B14,"Y","N")
• CO2 Met (Y/N) = IF(S20>B14,"Y","N") and so on.
Other Excel Equations
• No. of Students Attempted
• =COUNT(C20:C60), depends on the no. of students
• Threshold Marks for each question
• = C19*0.5 (50% of each question)
• No. of Students who got >=50%
• =COUNTIF(C20:C60, ">=" &C29)
• Percentage of students who got >=50%
• = (C30/B12) =(𝑁𝑜.𝑜𝑓 𝑆𝑡𝑢𝑑𝑒𝑛𝑡𝑠 𝑤ℎ𝑜 𝑔𝑜𝑡≥50%
𝑇𝑜𝑡𝑎𝑙 𝑛𝑜.𝑜𝑓 𝑆𝑡𝑢𝑑𝑒𝑛𝑡𝑠 ) X 100%
• No. of Students achieved CO
• =COUNTIF(R20:R60,"Y")
• Percentage of Students achieved CO
• = (R28/B12) =(𝑁𝑜.𝑜𝑓 𝑆𝑡𝑢𝑑𝑒𝑛𝑡𝑠 𝑎𝑐ℎ𝑖𝑒𝑣𝑒𝑑 𝐶𝑂
𝑇𝑜𝑡𝑎𝑙 𝑛𝑜.𝑜𝑓 𝑆𝑡𝑢𝑑𝑒𝑛𝑡𝑠 ) X 100%
• CO-wise Result
• =IF(R29>=B14, "Y", "N") (If the percentage of students achieved CO is greater than or equal to threshold, then show “Y”, otherwise “N”)
• Overall CO Attainment
PO Attainment Calculation
• At the beginning of each semester, module leader will set the CO-PO mapping and relationships between the assessment tools (e.g. Midterm, Semester
Final)
• The mapping should be mapped according to the level of correlation
• Low = 1, Moderate = 2 and High = 3
• PO attainment calculation is performed after getting the CO attainment results (Y/N).
13
PO Attainment Calculation (contd.)
• CO results will be coming from the same equation used for CO attainments
• PO1 percentage= (
𝑆𝑈𝑀(𝑃𝑂1 𝑙𝑒𝑣𝑒𝑙𝑠 𝑓𝑜𝑟 𝑤ℎ𝑖𝑐ℎ 𝐶𝑂 𝑟𝑒𝑠𝑢𝑙𝑡 𝑖𝑠 "𝑌")𝑆𝑈𝑀 𝑜𝑓 𝑎𝑙𝑙 𝑃𝑂 𝑙𝑒𝑣𝑒𝑙𝑠
)𝑋 100%
• For Example,
• PO1 percentage = 3+3
3+3 𝑋 100% = 100% (both CO1 and CO2 result is “Y”)
• PO4 percentage = 3
3+3 𝑋 100% = 50% (Only CO3 result is “Y”)
PO Attainment Calculation (contd.)
• PO attained calculation
• If the percentage of PO Attainment is greater than or equal to threshold (50%), then show “Y”, otherwise “N”.

Creating Course File
• Module Leaders have to create course file for his/her course
• Create one course file combining all section
• Course file should be maintained
• hard copy and
• soft copy (PDFs)
• The Top Page for the Hard Copy Course File can be found in the OBE
Template Folder in Google Drive
