🎓 Instructor Guide: TinyTorch Milestone Assessment System

Overview: Capability-Based Assessment

The TinyTorch Milestone System transforms traditional module-based grading into capability-based assessment. Instead of grading 16 separate assignments, you assess 5 major milestone achievements that represent genuine ML systems engineering competencies.

📊 Assessment Framework

Traditional vs. Milestone Grading

Traditional Approach:

• 16 individual module grades (often disconnected)
• Focus on code completion and correctness
• Students lose sight of the bigger picture
• Difficult to assess real-world readiness

Milestone Approach:

• 5 major capability assessments
• Focus on systems integration and real applications
• Students understand progression toward professional competence
• Clear mapping to industry-relevant skills

The Five Assessment Milestones

Milestone	Capability	Assessment Focus	Weight
1. Basic Inference	Neural network functionality	Mathematical correctness, architecture understanding	15%
2. Computer Vision	Image processing systems	MNIST accuracy, convolution implementation	20%
3. Full Training	End-to-end ML pipelines	CIFAR-10 training, loss convergence, evaluation	25%
4. Advanced Vision	Production optimization	75%+ CIFAR-10 accuracy, performance analysis	20%
5. Language Generation	Framework generalization	Character-level GPT, architecture reuse	20%
