Many people in state service can describe their own job in detail but cannot say what it would take to move to the next level. That gap is not a personal failing. Advancement in Minnesota state government runs through a classification system that most staff never see explained. Minnesota Management and Budget maintains job classification specifications, organized into career paths and job families, that describe the typical work and qualifications of each class. Each position also has a position description. MMB describes an accurate position description as a Human Resources requirement used primarily for classification and for filling vacancies. In practice, the duties written in a position description, compared against class specifications, are a large part of how a position is classified.
Because the system is technical, requirements for advancement often stay unspoken. Common patterns include: people learn what a promotion requires only by asking someone who already got one; stretch work goes to whoever is closest to the supervisor or whoever asks first; and the difference between being good at your current job and being ready for the next class is never named. These patterns tend to favor people who already have networks, confidence to ask, or time outside work to seek out information. Staff in DSD have described exactly this: unclear pathways and inconsistent recognition of their work. Those are patterns in how a unit operates, and they respond to practice.
A supervisor can change a lot without touching classification. You can say out loud what advancement in your unit usually requires and write it down. You can walk each person through the class series their position belongs to and point to the public class specifications. You can explain which experiences tend to matter for the next class, such as leading a workgroup, drafting policy or managing a contract, and which are nice to have. You can make sure every person hears this, not only the ones who ask.
What a supervisor cannot do is promise a reclassification, a promotion or a pay change. Those decisions belong to HR classification staff and, where a labor agreement applies, to labor relations. Being clear about that boundary is part of transparency. It protects staff from expectations no one can keep, and it tells them where the real decision sits.
