As PP have highlighted, the Bath 'advantage' is that placement years are available for all/nearly all degrees in across their departments and have been for many years. This means there is deep knowledge/expertise at a university and departmental level, that can be deployed to assist students.
As ever, there are caveats. Most placements are not guaranteed. You switch to the non-placement course variant if you are not successful. Much depends on a student's early engagement, persistence and resilience.
There is a regional dimension too. A large proportion of Bath's students are drawn from the SE, for whom access to London-based placements are more straightforward than for those from other regions. If your DC is SE-based, that they can really leverage the Bath advantage; if not, then the benefit is still there but possibly more tempered.
Finally, as is often pointed out on other threads, the departmental aspect needs to be considered and can sometimes trump the Bath advantage. Both Bath and York are well regarded for Politics and IR.
However, in the case of Chemistry, where York has a stronger reputation than Bath and partly because chemistry placement/job opportunities are not as London-centric as in the case of public policy or financial services, the employment statistics are not skewed decisively in Bath's favour.
