Though gifts cannot be taught, believers can grow in their expression and use of already-given gifts

Paul tells Timothy to "stir up" (anazōpyrein) his gift (2 Tim 1:6). Paul urges the Corinthians to eagerly desire prophecy (1 Cor 14). This implies growth in gift expression is possible. However, Mike warns against turning this into a systematic school (Bethel School of Supernatural Ministry). Old Testament "school of the prophets" is often invoked as a parallel but this is anachronism — filling an ancient phrase with modern content without historical study.
