Why Doesn't Professional Development Always Lead to Better Student Outcomes?

Summary of Insights  

• Professional development for teachers is most effective when it is sustained, job-embedded and connected to classroom practice.  

• One-time workshops rarely lead to lasting instructional change without follow-up coaching, collaboration and opportunities for reflection.  

• Effective professional learning is grounded in adult learning principles and helps teachers apply new knowledge in real-world instructional settings.  

• District and school structures play a critical role in supporting implementation through time, feedback, collaboration and leadership support.  

• Student outcomes improve when professional learning is part of an ongoing system of continuous improvement, rather than a single event. 

During my early teaching days, I had a “binder bookshelf” in my classroom, loaded with the notebooks and resources I collected during professional development workshops and conferences. Over time, those resources became digital notebooks, saved on thumb drives and in the cloud. Admittedly, once I collected my resources, they often sat on their physical or digital shelves, occasionally referenced, but more often forgotten amid the busy day-to-day activities of working with students. As a young teacher, I enjoyed professional learning and frequently sought it out, but I rarely had the time, support and capacity to effectively apply my learning and these new resources to my work.  

Looking back, I see that my early professional development sometimes was disconnected from my lived classroom experiences. While I liked the resources I received, often I had to deprioritize what I learned while I grappled with district requirements, curricular mandates and the significant social-emotional needs of my students. This disconnect is not atypical: high work pressure and a lack of shared learning experiences have been shown to yield greater dissatisfaction and a perceived lack of agency with professional learning among teachers.¹  

The Need for Better Teacher Professional Development 

Student access to well-qualified, well-prepared teachers is a mixed proposition in the United States, a phenomenon particularly acute in STEM teaching. The United States has persistent shortages in the number of middle and high school STEM teachers in hard-to-staff contexts such as rural, high-poverty and high-minority schools.² 

In middle school settings alone, 31% of math teachers and 24% of science teachers do not have degrees and/or certification in their in-field subject area³ – with schools in rural locations, southern states and high-poverty areas experiencing the greatest disparity in STEM teacher preparation, certification and classroom experience.⁴   In my home state of Texas, the number of uncertified teachers dramatically increased from 13,000 during the 2019-20 school year to approximately 42,000 in 2024-25.⁵ STEM education advocates point out that, given the gaps in experience and preparation K-12, STEM teachers need continued and intensive support with STEM content knowledge and access to research-based instructional practices.⁴ 

Given this context, it is not surprising that teacher professional learning is one of the largest instructional investments many districts make. Yet improved student outcomes or greater teacher satisfaction do not automatically follow those investments. Traditional implementation of STEM teacher professional development can fail the very audience it intends to support, especially if the training is disconnected from the district’s or school’s academic goals and STEM strategy, teachers’ day-to-day classroom needs or the development of teachers’ own STEM content knowledge, pedagogical content knowledge and STEM confidence and identity. 

Even training designed to help teachers identify impactful instructional techniques or implement high-quality instructional materials (HQIM) can miss the mark if it lacks research-based design principles, is too limited in duration, or fails to address the need for teachers’ ongoing planning, practice, reflection, collaboration and continuous improvement. A 2024 RAND survey on teacher satisfaction with HQIM professional learning illustrates the dilemma: 53% of participating teachers implementing HQIM reported spending less than two hours monthly in professional learning, and only 50% report that their professional learning was relevant and useful.⁶  A recent EdReports survey revealed that teachers found that their associated HQIM training inadequately prepared them for classroom implementation and was not of high quality; 22.8% of teachers reported receiving no implementation training at all.⁷   

A Vision for Impactful Professional Learning 

What is it about the design and delivery of professional development that fails to produce meaningful educator engagement and implementation, to substantively change instruction or produce lasting student outcomes? 

An increasing body of research suggests that periodic seminars or “one-and-done” training events often do not show sustained impact if they are not connected to a coherent vision, structural or policy alignment at the district and building levels, and sustained collaborative time to help teachers internalize and implement curricula and instructional strategies. Here is NMSI’s vision for impactful professional development and the strategies we’ve seen that help move the needle on student outcomes.  

Professional learning must be grounded in best practices for adult learning.  

Linda Darling-Hammond’s seminal study on effective teacher development remains important a decade after publication.⁸ Darling-Hammond’s research shows that impactful professional learning supports active learning, is of sustained duration, supports collaboration and opportunities for feedback and reflection, and models effective practice — characteristics which aren’t necessary found in one-off trainings. 

Effective professional learning allows teachers to experience content in hands-on, inquiry-based settings and practice instructional delivery with support and guidance from peers and coaches. Importantly, professional learning designers must recognize and respect participants’ expertise and experience as additional resources in training. 

Teachers should be given choice in how and when to engage with content and encouraged to practice new skills in low-risk, supportive environments. Effective professional learning allows teachers to anticipate challenges and potential barriers to student understanding, rehearse instruction through a practice-based facilitation model, and receive feedback from peers and instructors — reinforcing core teaching practices. 

For lasting results, none of these principles can be divorced from teachers’ real-time classroom needs, and they must be practiced and reinforced through on-going professional learning activities to be sustained. In short, to influence student outcomes, the workshop model must be positioned within a larger strategy that includes sustained learning over time, job-embedded instruction and coaching, peer collaboration and planning, and reflection on instructional practice.  
 

Sustained Impact Relies on Consistent Feedback and Year-Round Touchpoints. 

EdWeek’s recent special report “Beyond the ‘One-and-Done’: Professional Development that Sticks” spotlighted districts experimenting with the timing and format of professional learning to see what strategies drove both engagement with and application of professional learning. 

A common theme in these profiles is the intentional, ongoing learning opportunities that happen in formal and informal settings throughout the school year. Districts that broadened their professional learning strategy to include structured and collaborative professional learning communities, time for collaboration and planning, and routine instructional feedback found both greater transfer-to-practice and teacher satisfaction with their learning opportunities. 

Models in which teachers have the time and space to collaborate with peers, receive consistent coaching and feedback from mentors and peers, and that prioritize practice and continuous improvement show greater impact and sustainability than a traditional professional development event.⁹ In summation, workshops without follow-up, and professional learning events in isolation, rarely recoup the investment that districts are making in their staff.   
 

Research-based professional learning can only succeed in the right environment. 

While the research on impactful professional learning is widely known, often the very structures, policies and practices of districts and schools prevent effective and consistent implementation of these strategies and can lead to teacher dissatisfaction with their professional learning activities. 

For school leaders overseeing professional development strategy, research-based professional learning principles are enabled by a “whole school” support model that empowers outstanding teacher practice. For teachers to create invitational, highly impactful STEM classrooms, they must work in supportive environments that invite and cultivate teacher leadership, celebrate teacher inquiry and reflection, and use data effectively to invite more students into challenging, college and career-preparatory courses.  

These environments are created and sustained by district and school leaders who understand research-based best practices in STEM instruction so they can provide effective coaching and feedback to their faculty. Critically, they must create the structures, practices and time necessary for teachers to “try on” new instructional strategies and content. This means that school leaders should evaluate and rethink school schedules to prioritize opportunities for learning and collaboration, examine how professional learning communities are structured and run, and provide more opportunities for teachers to unpack and apply professional learning together.   

The Takeaway: Professional Learning Succeeds When District and School Structures Support Implementation 

As a designer of professional learning myself, I think deeply about the research-based conditions that need to be true for teachers to avoid creating their own binder bookshelves after professional learning. Thinking back to my early self, I know that the rich conversations and collaborations with my mentor, my principal and my peers about what I was learning and observing helped me transfer what I learned in workshops to my instructional practice. However, those connections were hard to come by, time was short and the business of the daily schedule and expectations impeded the very improvements I wanted to make.  

Professional learning succeeds when systems, policies and leadership prioritize implementation. Since our collective goal is better student outcomes, moving away from compliance, mandated attendance or completion metrics is a starting point; accompanying mandatory professional development days or workshops with job-embedded practice and collaboration is another. 

These aren’t easy solutions to scale and require sustained attention, resources and time, all of which are difficult to come by. Yet, professional learning is only as impactful as the framework we build to sustain it. If we want to see real instructional change, we should stop viewing professional learning as a one-time event and instead treat it as a prioritized, ongoing commitment to our teachers and our students.  

Move Beyond One-Time Training 

For professional learning to change classroom practice, it must be supported by systems that prioritize implementation, collaboration and continuous improvement. NMSI partners with districts to create the conditions that make professional learning stick.  

Frequently Asked Questions 

Why doesn't professional development always improve student outcomes?  Professional development doesn’t automatically lead to better student outcomes because attending a training session is not the same as changing classroom practice. Teachers often need time, coaching, collaboration and ongoing support to successfully implement new strategies and sustain instructional change. 

What makes teacher professional development effective?  Research suggests that effective professional development is sustained over time, supports active learning, includes opportunities for collaboration and feedback, and connects directly to classroom practice. Professional learning is most impactful when teachers can apply new knowledge, reflect on implementation and receive ongoing support. 

Why are one-time professional development workshops often ineffective?  One-time workshops can introduce new ideas, but they rarely provide enough time for educators to practice, refine and sustain new instructional approaches. Without follow-up support, many teachers struggle to translate workshop learning into long-term classroom implementation. 

What is job-embedded professional development?  Job-embedded professional development takes place within the context of a teacher’s daily work. Examples include instructional coaching, collaborative planning, professional learning communities, peer observation and ongoing feedback cycles. These approaches help teachers immediately apply new learning to classroom practice. 

How do professional learning communities support teacher growth?  Professional learning communities create structured opportunities for educators to collaborate, analyze student work, share instructional strategies and solve common challenges. Consistent collaboration helps reinforce professional learning and increases the likelihood that new practices will be implemented effectively. 

What role do school and district leaders play in successful professional development?  School and district leaders help create the conditions that support professional learning. This includes providing time for collaboration, establishing effective professional learning structures, supporting instructional coaching and creating systems that encourage continuous improvement rather than simple compliance. 

How should districts evaluate professional development effectiveness?  Districts should look beyond attendance records and completion rates. Effective evaluation includes examining changes in instructional practice, implementation of new strategies, educator feedback and evidence of impact on student learning and outcomes. 

How long does it take for professional development to influence student outcomes?  Meaningful instructional change typically takes time. Professional development is more likely to influence student outcomes when learning is sustained over months or years through ongoing coaching, collaboration, reflection and implementation support.
