ArchaeoTek Bio/Archaeological Techniques and Research Centre has announced its 2025 summer field schools for undergraduate and graduate students. Students gain archaeological and forensic experience in Europe. There is an option to pay for course credits, which students may be able to transfer to their home institution. Or, one can participate as a volunteer and not receive credit. (I didn't see a clear application deadline posted in my cursory reading of the announcement.)
