  1. Foundations: Evaluation Science & Python Tooling

    4 weeks
    Goals
    • Master core statistical concepts for evaluation: sampling, hypothesis testing, confidence intervals, Cohen's kappa
    • Set up a Python development environment with key evaluation libraries (HuggingFace Evaluate, NumPy, SciPy, Pandas)
    • Understand the landscape of AI benchmarks: MMLU, HumanEval, GSM8K, MT-Bench, BigBench, and their design philosophies
    Resources
    • HuggingFace Evaluate library documentation and tutorials
    • Stanford CS229 - Statistical Learning foundations
    • Paper: 'A Survey on Large Language Models' (2023) for benchmark overview
    • Python for Data Analysis by Wes McKinney
    Milestone

    You can implement a basic evaluation harness that loads a benchmark dataset, runs model inference, computes accuracy/F1 scores, and reports confidence intervals.

  2. LLM Evaluation Pipelines & Model Integration

    6 weeks
    Goals
    • Build end-to-end evaluation pipelines that integrate with multiple LLM providers (OpenAI, Anthropic, local models via vLLM)
    • Learn prompt engineering for evaluation: few-shot grading, chain-of-thought scoring, rubric-based LLM-as-judge approaches
    • Implement experiment tracking with W&B or MLflow for reproducible benchmark runs
    Resources
    • OpenAI Evals framework source code and documentation
    • Eleuther AI lm-evaluation-harness GitHub repository
    • LangSmith documentation for LLM tracing and evaluation
    • Weights & Biases evaluation tracking tutorials
    Milestone

    You can build a multi-provider evaluation pipeline that runs a standardized benchmark across 5+ models, logs results to W&B, and generates a comparison report with statistical significance tests.

  3. Adversarial Testing & Benchmark Design

    6 weeks
    Goals
    • Learn red-teaming methodologies: prompt injection, jailbreaking, benchmark gaming, and contamination detection
    • Design custom domain-specific benchmarks with proper dataset curation, difficulty stratification, and answer validation
    • Understand psychometric principles: item response theory (IRT), test-retest reliability, construct validity
    Resources
    • Paper: 'Do NLP Models Know Numbers?' and related probing studies
    • OWASP Top 10 for LLM Applications
    • NIST AI Risk Management Framework
    • Psychometric Theory by Nunnally & Bernstein (selected chapters)
    Milestone

    You can design a custom benchmark suite for a specific domain (e.g., financial document analysis) with contamination-resistant test items, automated scoring, and a methodology document suitable for external publication.

  4. Production-Grade Evaluation Infrastructure

    6 weeks
    Goals
    • Build CI/CD-integrated evaluation pipelines using GitHub Actions that gate model deployments based on benchmark thresholds
    • Implement containerized, reproducible evaluation environments with Docker and dependency locking
    • Design human-in-the-loop evaluation workflows with annotator management, quality control, and inter-rater reliability monitoring

    • Amazon SageMaker Model Monitor documentation
    • Label Studio for human evaluation annotation
    Milestone

    You can deploy a production evaluation system that automatically evaluates new model releases, gates deployments based on quality thresholds, maintains evaluation history, and alerts stakeholders to regressions.

  5. Specialization & Industry Impact

    4 weeks
    Goals
    • Deep-dive into a specialization: agent evaluation, multimodal benchmarks, RAG system evaluation, or safety/red-teaming
    • Contribute to open-source benchmark projects or publish original evaluation methodology

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Multi-Model LLM Comparison Dashboard

Beginner

Build a Python-based evaluation harness that runs 5 popular benchmarks (MMLU, HellaSwag, ARC, TruthfulQA, GSM8K) against 3+ LLM providers, stores results in a database, and displays a comparison dashboard with Streamlit or Gradio.
