Get connected with The Carpentries community.
Describe where you can go to get information on running a workshop.
In becoming a certified Carpentries Instructor, you are also becoming part of a community of like-minded volunteers. This section provides some background on The Carpentries organization, how to participate in one of our primary activities (running workshops), and other ways to get involved with the community.
A Brief History
Software Carpentry was founded in 1998 with the mission of teaching lab skills for research computing. Data Carpentry was founded in 2014 with the mission of building communities teaching universal data literacy.
Also in 2014, Library Carpentry was founded with the mission of teaching data skills to people working in library- and information-related roles.
On January 1, 2018, Software Carpentry and Data Carpentry merged their projects to form a new project called The Carpentries under the fiscal sponsorship of Community Initiatives. Within this new organization structure, Software Carpentry and Data Carpentry retain their individual identities as Lesson Programs of The Carpentries. On November 1, 2018, The Carpentries Executive Council approved Library Carpentry as the third official Lesson Program of The Carpentries.
The Carpentries project comprises communities of Instructors, Trainers, Maintainers, helpers, and supporters from Software Carpentry, Data Carpentry and Library Carpentry who share a mission to teach foundational computational and data science skills.
You can learn more about the history and goals of each Lesson Program by reading “Software Carpentry: Lessons Learned”, “Data Carpentry: Workshops to Increase Data Literacy for Researchers” and “Library Carpentry: software skills training for library professionals””.
Similarities and Differences between The Carpentries Lesson Programs
All lesson programs under The Carpentries share the same value of promoting efficient, shareable, and reproducible research practices. Their aligned missions are accomplished by running accessible, inclusive training workshops; teaching openly available, high-quality, community-developed lessons; and fostering an active, inclusive, diverse instructor community that promotes and models reproducible research as a community norm.
Similarities between Data Carpentry, Library Carpentry, and Software Carpentry workshops include:
- a focus on technical skills.
- a two-day format taught by volunteer instructors.
- a focus on filling gaps in current training for learners.
The major differences between Data Carpentry, Library Carpentry, and Software Carpentry workshops are their content and intended audience.
Data Carpentry workshops:
- are aimed at pure novices,
- are domain-specific,
- focus on best practices surrounding data, and
- present a full curriculum centered around a single data set.
Library Carpentry workshops:
- are aimed at people in library- and information-related roles,
- focus on best practices in data structure, and
- are modular—each Library Carpentry lesson is standalone.
- are sometimes less than two days.
Software Carpentry workshops are:
- intended for people who need to program more effectively to solve their computational challenges,
- not domain-specific, and
- modular—each Software Carpentry lesson is standalone.
In a visual representation, these similarities and differences look like this:
What is a Carpentries Workshop? The Rules.
Using the Names and Logos
The names “Data Carpentry”, “Library Carpentry”, and “Software Carpentry” and their respective logos are all trademarked. You may only call a workshop a Data Carpentry, Library Carpentry, or Software Carpentry workshop if:
- it covers the core topics (see below),
- at least one of the instructors is a certified Carpentries Instructor,
- you run our standardized pre- and post-workshop assessments and ensure everyone participates.
Note that the individual Data Carpentry, Library Carpentry, and Software Carpentry lesson materials are freely available under a permissive open license. This means that you may use them in contexts outside of a Carpentries workshop (e.g. as material introduced into a longer course, as a standalone 2-3 hour session, as homework exercises, etc.) provided you cite the original source.
It is only when you want to run a branded Carpentries workshop using the materials that the requirements listed above are needed.
What is the Core Curriculum?
A Data Carpentry workshop must include a Data Carpentry lesson on data organization and three other modules in the same domain from the Data Carpentry curriculum. Published curricula include the Ecology, Genomics, Social Science and Geospatial workshop materials. Additionally, Astronomy, Digital humanities, Economics and Image analysis curriculum are under development.
A Library Carpentry workshop must include three to four of the core lessons, which include an introduction to data, the UNIX shell, OpenRefine, and Git. Library Carpentry also maintains an “extended” set of lessons that can be taught in addition to the core curriculum These lessons are taught infrequently or are under development and include: SQL, webscraping, Python and an introduction to data for archivists.
A Software Carpentry workshop must include lessons on version control (e.g. Git), the UNIX shell, and a programming language (e.g. R or Python).
Within these guidelines, there is flexibility in which episodes of the lesson you cover, which exercises you use, and whether you include optional materials (e.g. callouts) and optional episodes.
Who Can Teach What
People who have gone through the two-day instructor training course and completed the the checkout process are considered “certified” Carpentries Instructors and can teach curricula for any of the lesson programs (Data Carpentry, Library Carpentry, and Software Carpentries) as they feel able. While Instructor badges may list a primary lesson program affiliation, Instructors are not required to certify separately for each. For more information, see the description of the Instructor checkout procedure.
Note that as long as you have at least one certified Instructor, the other instructors and helpers at a branded workshop do not have to be certified. We rely on the judgment of local organizers to recruit and orient volunteers who will embody The Carpentries ethos and practices.
There is a great list here in the handbook Helper Checklist and Suggestions.
How to Run a Carpentries Workshop
The Carpentries Handbook is a community-developed resource that provides tips, checklists, and points of contact for nearly all Carpentries-related activities in one location. The Carpentries Handbook is the definitive source for policies and information. Here, we will cover some information about actually running a workshop.
Briefly, there are two types of Carpentries workshops: centrally-organized and self-organized. Centrally-organized workshops are organized by a team of Regional Coordinators who take care of logistics and administration such as finding instructors and handling workshop registration. For self-organized workshops, the organization hosting the event is responsible for these details.
Workshops as an Instructor
As an Instructor, you may be primarily teaching at local workshops or you may not have local opportunities, or you may just want to teach somewhere else.
If you want to teach non-locally, you should be sure to join our Instructor mailing list during the community exercise below, so that you hear about upcoming teaching opportunities.
Note that The Carpentries does not guarantee that instructors will get to teach at workshops after they are trained, so the best way to make sure that you get to teach (if you want) is to try running a workshop or even a single lesson yourself. It can seem daunting to organize your own workshop, but as long as you have 1-2 people who can either help or co-instruct, The Carpentries Core Team and community can provide support and guidance so that it’s not so scary!
In both cases (self- or centrally-organized), you can start the workshop process by completing The Carpentries workshop request form.
For more details on how to run each type of workshop, see:
or the the following Lesson Program specific references:
Policies related to Instructor Training and workshops The Carpentries can be found in The Carpentries Handbook. Please be sure to read through the instructor no-show policy before signing up for your first workshop.
In order to communicate with learners, and to help us keep track of who’s taught what and where, instructors create a website with information about their workshop.
To ensure unique names for each event,
we use the
year-month-day-venue format for the identifier, the slug.
For instance, for a workshop that starts on Febuary 22nd, 2022
at the University of Data Skills,
the slug would be
If you are teaching a centrally-organized workshop,
please wait for the email from your regional coordinator
that will tell you the slug to use for your workshop.
Once that your workshop website has been created, the host or lead instructor sends its URL to the workshop coordinator, who adds it to our records. The workshop will show up on our websites shortly thereafter.
You may also create an Etherpad for your workshop
(or other Carpentries-related event).
When you point a browser to a url at
for the example above)
you will either arrive at an existing Etherpad by that name or a brand new
etherpad with basic Carpentries information at the top.
Practice With The Carpentries Infrastructure
Go to the workshop template repository and follow the directions to create a workshop website using your local location and today’s date. Put the link for your workshop website into the Etherpad.
This exercise should take about 25 minutes.
Note: Sometimes web browsers will cache the workshop webpage, so when you make changes in GitHub, they don’t show up on the workshop webpage immediately. Two ways to avoid this are to use a “private” or “incognito” mode in your web browser or by following these instructions to bypass your browser cache.
Question and Answer
What questions do you have about running and teaching at a workshop? Talk with a partner and enter your questions into the Etherpad. At this time we will also return to discuss questions remaining from the beginning of the day.
Leave about 10 minutes for this discussion.
A Culture of Contribution
In the same way that we hope to promote a culture of openness, sharing, and reproducibility in science and research through training researchers with the tools they need, The Carpentries organization itself aims to be open, collaborative, and based on best practices. We want to draw together the collective expertise of our teaching community to create collaborative lessons, share other materials, and improve the lessons via “bug fixes” as we go along. Our Help Wanted page lists issues for which lesson maintainers need assistance and is a good place to start when looking for ways to contribute.
Maybe this instructor training has inspired you to go home and write your own fantastic lesson! If you’d like to model it after the Software, Data and Library Carpentry lesson format, you can find a template and instructions in The Carpentries lesson example repository, and a place to develop it in The Carpentries Incubator.
Any lesson that uses The Carpentries lesson template, follows our Code of Conduct, and is licensed either CC-BY or CC-0 can be hosted in The Carpentries Incubator. Another resource, The Carpentries Curriculum Development Handbook, provides a guide to the backwards design approach we recommend for lesson development.
Many Ways to Contribute
We recognize that the medium of GitHub may be restrictive to those who wish to contribute to our lessons. We are always searching for ways to make the process more friendly to all, whether that be contribution training, or alternative routes to contribution. If you have any ideas how we might make contribution more contributor-friendly, please let us know.
Being part of a friendly, open discussion, is of equal or greater importance to the community than submitting the perfect lesson change. The checkout process to become a certified Instructor will be one way to start connecting to the community and find which area will allow you to contribute best.
The Carpentries Community
As you can imagine, based on the above, there are many aspects of running The Carpentries! While there are a small number of dedicated Core Team members who work for The Carpentries organization, the real power of The Carpentries is in its community of volunteers that take on all sorts of roles to teach and organize workshops, help produce and maintain lessons, and most importantly, build local and global communities of practice around skills for data analysis, computational thinking, and research software development. Our community depends on individuals like you who are passionate about expanding these communities of practice through inclusive and evidence-based instructional practices, and can contribute your perspective and expertise to continually refine our instructional materials and practices. A full description of the breadth and diversity of community member roles, an overview of The Carpentries various social media channels, a calendar of future community events, and descriptions of mailing lists used by the community can be found here on The Carpentries website and also on the getting connected page.
Participating in The Carpentries – What’s Your Role?
If you are at an in-person training, your Trainer will hand out paper copies of a worksheet. If you are at an online training, you can get a digital copy here.
Take a moment to review member community roles on The Carpentries community website. Working on your own, match up the roles with the descriptions. When you are done, think about the question at the bottom of the worksheet about what roles you might play, and enter your thoughts in the Etherpad.
