  2. Statistical Modeling for Workforce Data

    6 weeks
    Goals
    • Master survival analysis (Cox proportional hazards) for time-to-event workforce questions
    • Learn causal inference methods (diff-in-diff, propensity score matching) for HR intervention evaluation
    • Build your first predictive attrition model using scikit-learn and XGBoost
    Resources
    • Book: 'Causal Inference: The Mixtape' by Scott Cunningham (free online)
    • Kaggle: IBM HR Analytics Attrition Dataset for practice
    • Datacamp: Survival Analysis in Python course
    Milestone

    You can build, validate, and interpret predictive models for employee outcomes using appropriate statistical methods.

  3. NLP & LLMs for People Data

    5 weeks
    Goals
    • Apply sentiment analysis, topic modeling, and named entity recognition to employee text data
    • Build a RAG pipeline over HR policy documents using LangChain and OpenAI
    • Learn prompt engineering techniques specific to HR content classification
    Resources
    • HuggingFace NLP Course (free)
    • LangChain documentation and HR-specific tutorial notebooks
    • Practice: Fine-tune a BERT model for classifying exit interview themes
    Milestone

    You can build end-to-end NLP pipelines and LLM-powered assistants for HR use cases.

  4. Ethical AI, Bias Auditing & Compliance

    4 weeks
    Goals
    • Learn frameworks for fairness assessment: disparate impact, equalized odds, demographic parity
    • Use AI Fairness 360 and SHAP to audit model bias in hiring and promotion models
    • Understand GDPR, EEOC guidelines, and NYC Local Law 144 implications for AI in HR
    Resources
    • IBM AI Fairness 360 toolkit documentation and tutorials
    • Book: 'Weapons of Math Destruction' by Cathy O'Neil for ethical context
    • SHAP library documentation with HR model examples
    Milestone

    You can audit any HR ML model for bias, produce compliance-ready documentation, and recommend mitigation strategies.

  5. Data Engineering & MLOps for People Data

    5 weeks
    Goals
    • Design ETL pipelines that integrate data from Workday, ATS, survey tools, and collaboration platforms
    • Learn dbt for analytics engineering on HR data models
    • Deploy and monitor ML models using SageMaker or Vertex AI with proper MLOps practices
    Resources
    • dbt Learn (official free courses)
    • AWS SageMaker documentation and tutorials
    • Practice: Build an end-to-end pipeline from Workday API → Snowflake → dbt → Tableau
    Milestone

    You can architect production-grade data and ML pipelines for people analytics at scale.

  6. Executive Communication & Capstone Project

    4 weeks
    Goals
    • Master data storytelling techniques for non-technical HR and C-suite audiences
    • Build a comprehensive workforce intelligence platform as a portfolio capstone
    • Develop a consulting-ready presentation that demonstrates business impact
    Resources
    • Book: 'Storytelling with Data' by Cole Nussbaumer Knaflic
    • Practice: Create a full People Analytics case study with executive summary, technical appendix, and dashboard
    • Join SHRM People Analytics community and People Analytics World events for networking
    Milestone

    You have a polished portfolio, can present to HR executives, and are ready to interview for AI People Data Scientist roles.

Practice Projects

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

Employee Attrition Predictor with Explainable AI

Intermediate

Build a predictive model using the IBM HR Analytics dataset (or a synthetic equivalent) that forecasts which employees are at risk of leaving within 6 months. Deploy SHAP-based explanations in a Streamlit dashboard so HR business partners can understand why each employee is flagged.

~25h
Predictive modelingFeature engineering for HR dataModel explainability (SHAP)

NLP Pipeline for Employee Survey Analysis

Intermediate

Ingest 10,000+ simulated open-ended employee survey responses and build a pipeline that performs topic modeling (BERTopic), sentiment analysis, and keyword extraction. Create a Looker/Tableau dashboard that visualizes themes over time and by department.

~20h
NLP and text analyticsTopic modelingData visualization

HR Policy RAG Assistant

Advanced

Build a retrieval-augmented generation system using LangChain, OpenAI embeddings, and a vector database (Chroma or Pinecone) that allows employees to ask natural-language questions about company policies. Evaluate retrieval quality and add guardrails for sensitive topics.

~30h
