THE STORY BEHIND CSUK ONE

          
Built by a teacher.
Made for what’s next.

          
CSUK began in 2015 with a simple idea: give Computer Science teachers the tools and confidence to make every lesson count.

          
More than a decade later, that idea has grown into something bigger. CSUK One brings learning, coding, assessment and teaching together in one connected home — shaped by the realities of classrooms, not just a software roadmap.

 FOR OUR EXISTING CSUK COMMUNITY
Your CSUK journey
continues.
CSUK One is the next chapter of everything we've built together. And the most important thing to know? There’s no need to rush.
See how it works 

          
        

        
✓
Your existing CSUK platforms remain available during the transition.
Continue with your current classes and work while you get to know CSUK One. We're planning an extended period with both experiences running alongside each other.

        
PEACE OF MIND
What's changing — and what's not.
Your teaching plans matter. That's why this is an evolution you can explore gradually, rather than a sudden switch.

Keep teaching as normal
Continue lessons, assignments and existing groups on the CSUK platforms you already use.

YOUR NEXT STEPS
A simple way to make the move.
There’s no single right moment to switch. Here's the approach we'd recommend.

          
01
Carry on with your existing classes.
Finish the units, assessments and assignments already in progress. You don't need to interrupt your teaching.
NOW
02
Take a look around CSUK One.
Explore the connected courses, Code Studio, daily practice and teaching tools available to your account.
WHEN READY
03
Prepare your new classes.
Set up groups and student enrolments in CSUK One, using available class import tools where supported.
NEXT
04
Start fresh learning in the new workspace.
Choose a natural point — such as a new topic, term or class — to begin assigning work in CSUK One.

i
One important detail about student progress
Completed student work, historical results and progress from existing CSUK platforms do not automatically transfer into CSUK One. Those records remain on the original platforms during the transition. Importing or recreating a class is different from importing its previous results.

        
COMMON QUESTIONS
The things you might be wondering.

          
Do I need to buy another membership to try CSUK One?
Not necessarily. Qualifying existing CSUK memberships are recognised and provide access to corresponding CSUK One areas. The exact features depend on your current membership. The free CSUK One tools are available without purchasing a paid pack.

          
Will my current classes and assignments still work?
Yes — continue using your current groups, courses and assignments on the existing platforms during the transition. CSUK One is a separate workspace, so you can prepare new groups and activities there without interrupting current work.

          
Will my students' existing results move across?
No. Historical results, completed activities and progress do not automatically migrate into CSUK One. They remain on the original platform during the transition. Class enrolments may be set up or imported where supported, but this does not bring across assessment history.

          
When will the older platforms close?
We're planning a long transition with the existing platforms and CSUK One available side by side. We haven't announced a final shutdown date here. Any future changes will be communicated clearly so you have time to plan.

          
What is CSUK One, exactly?
It's a connected home for CSUK's teaching resources, interactive learning, coding, daily practice, quizzes, exams, progress reporting and classroom tools. Instead of moving between separate CSUK experiences, the aim is to bring the tools you need together in one place. Available areas depend on your account and memberships.

          
What if I'm not sure what my school has access to?
Get in touch and we'll help you understand your current membership, the corresponding CSUK One access and the best next step for your classes.

A few questions.
Clear answers.

            
Whether you're discovering CSUK One for the first time or already part of CSUK, here's what you need to know.

          

          
        

      


      

        

        

          
All questions10 answers

          

            

              01What can I use for free?
              
Quite a lot! Your free CSUK One workspace includes Daily Bytes (6-a-Day, Algorithm a Day and Type a Day), Python, HTML and Blocks coding environments, saved coding projects, interactive learning tools and extra-curricular activities.
For teachers, the free foundation also supports creating classes, enrolling students and viewing basic progress — so you can get started before choosing any paid packs.
✦ Your free account stays available, even after your full-platform trial ends.

            

            

              02Can I try the entire platform before buying a pack?
              
Yes! Once you have created your free account, you can activate a trial of the entire CSUK One platform — whenever you are ready. There is no need to start your trial the moment you sign up, so you can explore the free tools first and choose the right time to experience everything else.
During your trial, you can explore the paid features and discover how CSUK One could support your learning or teaching. When your trial ends, the paid areas become locked again unless you purchase access, but your free account and all the free features remain available. You can carry on using the free platform for as long as you like.
✦ Start your trial when it suits you. Keep your free access afterwards.

            

            

              03Do I need to install anything?
              
CSUK One is a browser-based platform. You can access its online learning and teaching workspace through a supported modern web browser, without installing a separate desktop application.

            

            

              04How do paid packs work?
              
Paid packs extend your free account with the content and capabilities you need. Schools can choose the curriculum, coding and teaching-resource packs that suit them, rather than having to purchase everything at once.
Explore the audience-specific access options above for current inclusions and pricing. What you can access depends on the packs or membership you hold.

            

            

              05Can schools add more packs later?
              
Yes. Schools can start with the areas they need now and add other available packs later as their requirements grow. Different packs unlock different curriculum content, resources and learning experiences.

            

            

              06Can I join as an individual student?
              
Yes. CSUK One is designed for independent learners as well as schools. Students can explore the free workspace and choose individual learning access for supported GCSE or A-Level study without requiring a school to buy a membership.

            

            

              07Can I create accounts for my children?
              
CSUK One includes a home-educator route designed to help parents support their children's Computer Science learning. Home-educator access provides a limited number of learner accounts, with structured learning, coding and progress visibility according to the chosen membership.

            

            

              08Can I use CSUK One as a tutor?
              
Yes. Tutor access is designed for supporting a small number of learners, assigning work and reviewing their progress. Explore the tutor option in the audience section to see the available membership and learner-account allowance.

            

            

              09What happens to the existing CSUK platforms?
              
CSUK One is the next evolution of CSUK, bringing teaching resources, coding, courses and assessment together. The existing platforms will continue running alongside CSUK One during an extended transition period.
There's no need to abandon current classes or unfinished courses. You can continue teaching on the existing platforms while exploring CSUK One at your own pace.

            

            

              10Will my membership, classes and progress move across?
              
Qualifying existing memberships are recognised for access to the corresponding areas of CSUK One. Class and student enrolments can be set up or imported where supported, but completed student work, assessment history and progress do not automatically transfer.
Keep using your current platforms to finish existing work and move new teaching activities over when you're ready. There's no confirmed deadline for switching.
