The ML Alignment & Theory Scholars program (MATS, formerly SERI MATS) is an education and research mentorship program for emerging AI safety researchers. This summer, we held the fourth iteration of the MATS program, in which 60 scholars received mentorship from 17 research mentors. In this post, we explain the elements of the program, lay out some of the thinking behind them, and evaluate our impact.

Summary.

Key details about the Summer 2023 Program:

Educational attainment of MATS scholars:
- 30% of scholars are students.
- 88% have at least a Bachelor's degree.
- 10% are in a Master's program.
- 10% are in a PhD program.
- 13% have a PhD.
If not for MATS, scholars might have worked at a tech company (41%), upskilled independently (46%), or conducted research independently over the summer (50%). (Note: this was a multiple-choice response.)

Key takeaways from our impact evaluation:

MATS scholars are highly likely to recommend [...]
