There are a lot of more recent academic studies:

Here's one paper from 2020 which gives a good overview

Key findings

The impact of professional development on pupils

• High-quality CPD for teachers has a significant effect on pupils’ learning outcomes. CPD programmes have the potential to close the gap between beginner and more experienced teachers: the impact of CPD on pupil outcomes (effect size 0.09) compares to the impact of having a teacher with ten years’ experience rather than a new graduate (0.11). CPD also has similar attainment effects to those generated by large, structural reforms to the school system (0.1).   
• Evidence suggests that quality CPD has a greater effect on pupil attainment than other interventions schools may consider, such as implementing performance-related pay for teachers or lengthening the school day.
• Teacher CPD may be a cost-effective intervention for improving pupil outcomes: while there are other interventions with a larger impact on pupil attainment, such as one-to-one tutoring (0.28), these programmes are typically far more expensive.
• CPD programmes generally produce positive responses from teachers, in contrast to other interventions. Large, structural changes to the school system, while as effective at improving pupil outcomes, incur substantial costs in terms of staff turnover and dissatisfaction.

The impact of professional development on teacher retention

• Increasing the availability of high-quality CPD has been shown to improve retention problems, particularly for early-career teachers. While factors other than access to CPD tend to be behind teachers’ decisions to quit the profession, there is evidence supporting targeted CPD programmes for teachers in the early stages of their careers.
• Induction training and mentoring programmes are particularly effective for improving retention rates early on. Quality CPD has the potential to alleviate acute retention problems for early-career teachers.
