Here’s a structured Activity 2: CO Attainment Calculation using the direct assessment method, a critical part of Outcome-Based Education (OBE) implementation.
🎯 Activity Title: CO Attainment Calculation (Direct Method)
🧩 Activity Objective
To enable participants to:
-
Understand how to calculate Course Outcome (CO) attainment using direct assessment.
-
Interpret attainment levels and relate them to targets set by the department.
-
Learn how to analyze student performance and identify areas for improvement.
🧑🏫 Facilitator Preparation
Before the session:
-
Prepare mock student assessment data for a sample course.
-
Prepare an Excel or print version of:
-
CO–Question mapping
-
Assessment scores
-
Attainment level formula
-
Target attainment levels
-
📘 Overview for Participants
-
Direct method involves using actual student performance on mapped questions from internal/external exams.
-
Attainment is computed by comparing actual performance with predefined targets (e.g., 60% students should score at least 50% in CO-related questions).
-
Attainment levels are typically:
-
Level 1: Target met by 40–59% students
-
Level 2: 60–69%
-
Level 3: ≥70%
-
📚 Sample Course: Data Structures
CO–Question Mapping
| CO No. | Questions in Assessment |
|---|---|
| CO1 | Q1 (5 marks), Q2 (5 marks) |
| CO2 | Q3 (10 marks) |
| CO3 | Q4 (10 marks), Q5 (10 marks) |
Mock Student Scores (Sample of 5 Students)
| Student | Q1 | Q2 | Q3 | Q4 | Q5 |
|---|---|---|---|---|---|
| S1 | 4 | 5 | 7 | 8 | 7 |
| S2 | 2 | 3 | 6 | 5 | 6 |
| S3 | 3 | 4 | 5 | 9 | 8 |
| S4 | 5 | 4 | 9 | 9 | 6 |
| S5 | 3 | 4 | 7 | 6 | 5 |
🧮 Step-by-Step CO Attainment Calculation
Step 1: Calculate Total Marks for Each CO per Student
Example for CO1 (Q1 + Q2 = 10 marks)
| Student | CO1 Score |
|---|---|
| S1 | 9 |
| S2 | 5 |
| S3 | 7 |
| S4 | 9 |
| S5 | 7 |
Step 2: Determine Threshold (e.g., 50% of CO total = 5 marks)
Step 3: Count Students Who Scored ≥ Threshold
-
For CO1, students who scored ≥5: All 5 students
-
% students attaining CO1: 100%
Step 4: Assign Attainment Level
| CO | % Students ≥ Threshold | Attainment Level |
|---|---|---|
| CO1 | 100% | 3 |
| CO2 | 80% | 3 |
| CO3 | 60% | 2 |
(Threshold and levels can be customized based on your institution’s policy.)

Table 2: Participant Calculation Table
| CO | Total Marks | Threshold (50%) | No. of Students ≥ Threshold | % Students | Attainment Level |
|---|---|---|---|---|---|
| CO1 | 10 | 5 | 5 | 100% | 3 |
| CO2 | 10 | 5 | 4 | 80% | 3 |
| CO3 | 20 | 10 | 3 | 60% | 2 |
