A search for CTE in the ERIC database included this result. The highlighted words used to describe the document may be useful in future searches.
A search for vocational education in the SU Descriptors field includes results for CTE, Career and Technical Education.

Search Google Scholar to find "future" sources that cite the article you already have.
