How can I tell whether students in a laboratory receive enough individual guidance?

Rather than relying only on a laboratory’s description, check how often students meet their supervisor, how they ask questions, what feedback they receive on research plans and results, and whether other faculty members or senior students provide support. Ask current students not only about the student-to-faculty numbers but also how easy it is to seek advice and whether there are periods with little guidance, then compare their answers with official information. Details vary by faculty and laboratory.
