Have you ever taken a look at teacher salary schedules only to be left confused by some of the terminology? Phrases like master’s +30 or master’s +15 are as technical as they are confusing, even for experienced educators. However, understanding what these terms mean can help you make informed decisions about your career and earning potential.
So, let’s get this out of the way: Ѳٱ’s +15 and master’s +30 simply refer to 15 or 30 graduate credits earned after completing a master’s degree in education or a related education field. These “plus” lanes are often one of the most efficient ways for a public-school teacher to increase teacher salary without committing to a doctorate. Still confused? Read on and learn more about this terminology.
What Does Ѳٱ’s +15/30 Mean
A master’s +15 or master’s +30 builds on an existing master’s degree, such as a master’s in education (M.Ed.) or another master of education degree program. Instead of earning a second full education degree, teachers complete additional graduate courses beyond their original graduate program.
These additional graduate credits are commonly recognized in K-12 school districts. Many teacher salary schedules include lanes that reward continued education, making this pathway especially relevant for educators working in a public school setting.
How Ѳٱ’s +15 and +30 Work in Education
Graduate credits toward master’s +15 or +30 are typically earned through approved, structured learning experiences. These are not random classes, but courses that meet specific academic and district standards. Before enrolling, teachers should understand where their credits can come from. Common sources include the following:
- University-based graduate courses offered online or in person
- District-approved professional development that can convert to graduate credit when approved by an accredited institution
- Programs offered through accredited institutions and recognized professional organizations

Ѳٱ’s +15/30 and Teacher Salary Lanes
Most public school districts use a step and lane system to determine teacher salary. This system rewards both years of experience and level of education:
- Steps move vertically and reflect years of service
- Lanes move horizontally and reflect academic credentials, such as a bachelor’s degree, a master’s degree or additional graduate credits
Moving from a master’s degree to master’s plus 30 can result in noticeable pay increases. The exact amount varies by state and school district, but districts generally reward advanced education because it supports stronger instruction and ongoing professional development.
How to Earn the Credits
Compared to completing another full degree program, earning master’s +15 or +30 credits can be more flexible. In fact, teachers often choose options that fit around their classroom responsibilities and personal schedules. Many educators turn to university graduate courses, online education programs or district-supported professional development. Additionally, stackable learning options and micro-credentials are also becoming more common.
For example, educators exploring trends in professional development may find it helpful to read about micro-credentials and how stackable courses are evolving educator professional development. Research on evidence-based professional development can also guide decisions about meaningful learning experiences.

What Counts?
Before signing up for any graduate courses, it is important to understand your district’s rules. Requirements can differ, so a little planning goes a long way.
- Make sure credits come from an accredited institution so your district accepts them
- Check that courses are relevant to your certification area if your district requires it
- Review your local collective bargaining agreement or HR handbook before enrolling
Benefits Beyond the Paycheck
While higher teacher salary is a major motivator, the benefits of master’s +15 or +30 go beyond pay. For instance, additional graduate credits often introduce new instructional strategies, refresh subject knowledge and support long-term professional growth.
These credits can also help with recertification requirements and strengthen a teacher’s professional profile. Building a strong record of learning, along with a thoughtful teaching portfolio, can open doors to leadership roles and expanded responsibilities. Ultimately, it’s important to understand that a master’s +15 or +30 is more than a line on a salary schedule. It is a strategic investment in both financial stability and classroom expertise.
