A harmonized longitudinal academic records dataset for higher education analytics

Description

This repository contains anonymized and harmonized longitudinal academic data derived from undergraduate students enrolled in an automotive engineering program at an application-oriented university in Vietnam. The 1,656 student records were drawn from five admission-year cohorts and multiple curriculum versions. Differences in course naming, coding, semester placement, and elective pathways required data cleaning, standardization, and cross-cohort harmonization across curriculum versions. Two parallel final datasets are provided, each containing 1,656 student records and 56 variables: a labeled version for direct interpretation and a harmonized coded version for analytical reuse and reproducible workflows. The released variables include student-level contextual information, 50 harmonized course-grade variables, cumulative academic performance, scholarship-related information, and academic-status variables. The two 56-variable datasets do not contain a separate admission-year or cohort identifier. The repository also includes course and variable dictionaries, an executable Python preprocessing file, a synthetic source-formatted course-grade dataset, aggregate audit summaries, a de-identified source-course extract documenting the pre-harmonization data structure, a README file, and supplementary semester-based and subject-group analytical outputs. The public reproducibility materials illustrate the programmatic course-grade harmonization stage only. They do not reproduce the private database extraction, administrative-record merge, manual reconciliation, anonymization, or final 56-variable coding steps. The de-identified source-course extract contains generalized metadata. Exact cohort and admission-year labels, group sizes, and links between the original and public groupings are not released. The original institutional administrative records and institution-specific harmonization mappings are not publicly available.
