“PD 360 is a central component in Clarendon One’s professional improvement program. Because it meets expectations and answers real issues, feedback from a recent teacher survey was very positive. It is individualized, convenient, and targeted. I suggest that other districts look into it.”

Clarendon County, South Carolina is often described as a paradise, with small-town atmosphere, near the Santee Wildlife Refuge, as well as breath-taking beaches and mountains close enough for weekend trips.

Clarendon School District One is a small, rural district of four schools and approximately 950 students with a 97 percent minority enrollment. This diversity brings both opportunities and challenges; therefore, concentrated efforts by teachers and administrators are made to "channel" the challenges into positive growth for all students.

Recent district highlights have included the following:


The Clarendon One professional learning department is currently focused on the following needs:


Clarendon One Assistant Superintendent Barbara Ragin and Dr. Robert Petrulis, an evaluation and research consultant working with the high school’s School Improvement Grant project and the district’s Math Science Partnership, have years of experience and are extremely knowledgeable about raising student success.  

Since 2010, the district has been using PD 360 to meet teacher needs. Ms. Ragin and Dr. Petrulis are pleased that School Improvement Network’s Educator Effectiveness System components PD 360, Observation 360, and Common Core 360 are addressing and impacting Clarendon One issues.

Differentiated Professional Learning

Teacher education, like student instruction, should meet a variety of abilities and be adaptive to evolving needs. With 3,000+ video segments on 125 topics from 120 experts, PD 360 ensures that Clarendon One teachers of all experience levels will find individual support to improve classroom strategies.

Continuous Student Improvement

Clarendon One administrators want student improvement to be a continuous process by which students are regularly monitored, assessed, and responsible for their own learning. Relevant PD 360 programs include Student Involvement in Assessment, Assessment for Learning, Accountability for Greater Student Learning, and Practical Student-Centered Learning—Instilling Ownership and Responsibility.

WIN Support

The South Carolina Writing Improvement Network serves as a professional learning resource for school administrators and teachers. PD 360 programs such as Curriculum Integration, Writing Across the Curriculum, and Reading, Writing, Speaking, and Listening wholly support WIN.


Professional Learning Communities (PLCs)

PD 360 is a great study resource and conversation starter for Clarendon One’s PLCs. Groups determine a topic, watch a relevant video segment individually before the meeting or together during the meeting, then discuss as a group how to apply the practices in their classrooms.


Classroom observations are significant to Clarendon One teacher evaluations and Observation 360 makes them even more effective. Administrators are able to give immediate feedback to teachers and recommend PD 360 segment links applicable to the individual’s needs.

Meaningful Reflective Practices

After watching a PD 360 segment, Clarendon One teachers answer reflection questions designed to stimulate thinking about classroom ap­plication. The answers are helpful to teacher and administrator to track growth, application, and knowledge.

Common Core Standards

Clarendon One is using Common Core 360 to expose educators to Common Core Standards, and next year they will use the tool to sustain full implementation and prepare educators to ready 100% of students for college and career.

Goals-Based Evaluation Action Plans

Continuing contract teachers must be evaluated at least once every three years as part of the progress process. Teachers develop individual Goals-Based Evaluation Action Plans consisting of goals, strategies, and activities to attain goals plus completion results. PD 360 programs are commonly included.


Dr. Petrulis has found that administrators as well as teachers love PD 360 because it targets specific needs in classroom management, teaching strategies, and assessments.

Actual Classroom Examples

PD 360 programs feature a variety of real classroom examples to illustrate strategy implementation. This is fundamental for teachers learning how to incorporate the practices into their own classrooms.

Interactive Learning Communities

Clarendon One teachers participate in PD 360’s interactive learning communities that allow conversations with other educators around the world. These communities focus on a shared instructional topic, goal, or committee research thus reducing the classroom isolation teachers often experience.


Clarendon One teachers are happy to have the flexibility to access PD 360 at home or work as well as the capability to take charge of personal growth with unlimited access.

“Clarendon One teachers are required to document their professional growth, and PD 360’s convenience makes it a popular choice for doing so. It is also useful in their Goals-Based Evaluation Action Plan strategies.”

“All teachers like to see how strategies are put into practice, and the ability to view real classroom implementation is significant in teacher education.”

“Campus administrators and teachers find that the online learning approach through PD 360 lends itself to individualization and customization of learning and professional growth.”

Barbara Ragin
Assistant Superintendent
Clarendon School District One, South Carolina 

“When considering the more appropriate and cost-effective methods for addressing the diverse needs of certified personnel and campus administrators, I certainly would advocate for the purchase and use of PD 360. In fact, I strongly recommend it as the initial purchase or replacement of other approaches to systematic professional development. This is an investment that pays great dividends relative to enhanced content knowledge of teachers, improved classroom practices, and ultimately increased student success!”
