Psychometric Engineering

Unlock the Future of Assessment: Advanced Psychometric Engineering with R From Data Cleaning to High-Stakes Reporting: A Professional Certification for PhDs and Researchers. Section 1: The Vision In today’s data-driven landscape, simply "running an analysis" isn't enough. Modern psychometrics requires the ability to engineer fair, stable, and theoretically sound measurement systems—and the communication skills to defend them to ministries, boards, and global stakeholders. Transform your research from raw numbers into actionable policy. Section 2: The Hybrid Learning Advantage Designed for busy professionals and doctoral candidates, this course combines the flexibility of self-paced learning with the rigor of live academic mentorship. Self-Paced Excellence: Access high-definition, pre-recorded modules that break down complex R code and psychometric theory step-by-step. Live Interactive Sessions: Join our Bi-Monthly Live Clinics where Dr. Metibemu reviews your code, answers theoretical questions, and discusses real-world case studies. Lifetime Access: Revisit the video library and R-script templates whenever you need them for future projects. Section 3: 15-Week Curriculum & Skills Level Focus Key Skill Milestone Weeks 1-2 R Fundamentals Build a reproducible environment and clean "dirty" assessment data. Weeks 3-4 CTT & Item Audit Identify "broken" items and dead distractors in high-stakes exams. Weeks 5-6 G-Theory Optimize testing budgets by decomposing error facets and rater severity. Weeks 7-8 Factor Analysis Statistically prove the dimensionality and theoretical structure of your scale. Weeks 9-12 Advanced IRT Master Dichotomous, Polytomous, and Multidimensional (MIRT) models. Weeks 13-14 Equating & Fairness Align scores across years and conduct legal "Fairness Audits" (DIF). Week 15 Interactive Apps Deploy Shiny dashboards to visualize Test Information Functions. Section 4: The Reporting & Lab Advantage We don't just teach you how to code; we teach you how to write for impact. Every module includes a Laboratory Assignment and a Technical Reporting Task: The "Management Memo": Practice explaining complex Stocking-Lord equating methods to a non-technical Registrar. The Fairness Audit: Learn to detect and report Differential Item Functioning (DIF) to ensure your test is legally defensible. The Model Fit Brief: Summarize CFA indices ($RMSEA$, $CFI$) into a "Pass/Fail" verdict for theoretical alignment. Section 5: Capstone Project The National Assessment Audit: You will be handed a raw dataset of 10,000+ responses from a national certification body. Your goal? Produce a 20-page Standardized Test Technical Manual covering item calibration, equity audits, and score equating. Section 6: Investment & Enrollment Course Fee: ?50,000 Flexible Payment: Installment option allowed (Maximum of two installments). Initial deposit required to access Module 1. Includes: Pre-recorded lectures, 2 Live Zoom clinics/month, R-Script templates, and 24/7 access to the Psychometric Clinic community.

This professional certification program transforms PhDs and researchers into expert psychometric engineers. You will master the complete pipeline of modern assessment, from data cleaning and classical analysis to advanced IRT, fairness auditing, and equating, using the power and reproducibility of R. Beyond analysis, the curriculum is uniquely designed to hone your technical communication, teaching you to defend complex methods and findings to ministries, boards, and global stakeholders through structured reporting. Delivered via a hybrid model of self-paced video modules and live mentorship clinics, the 15-week course culminates in a capstone project where you produce a full Technical Manual for a national assessment. Graduates will be equipped not just to analyze data, but to engineer fair, stable, and legally defensible measurement systems that inform policy and high-stakes decisions.
