I've seen lots of ATL skills maps. Like many other MYP Coordinators around the world, I've created ATL skills maps (because the IB doesn't provide them). But what I haven't seen much of is a skills progression. The IB provides the following framework for identifying skill competency, but it's still vague in terms of the level of complexity expected at each phase/level of competency.
Novice/beginning — students are introduced to the skill, and can watch others performing it (observation)
Learner/developing — students copy others who use the skill and use the skill with scaffolding and guidance (emulation)
Practitioner/using — students employ the skill confidently and effectively (demonstration)
Expert/sharing — students can show others how to use the skill and accurately assess how effectively the skill is used (self-regulation)
So I asked ChatGPT to generate a progression of skills, using the novice, learner, practitioner, and expert framework. I had to input several prompts to get exactly what I was looking for, but in the end it produced something that I think is a pretty good starting place. I ended up with two versions -- one which makes a start at articulating a progression of the individual skills and one which is much more streamlined and articulates a progression of the skill clusters. Like many IB educators, I find the ATLs a bit overwhelming -- how is it possible to explicitly (and meaningfully) teach over 130 skills? The streamlined approach allows for more flexibility and recognises the overlap of many of the skills.
Unlike the conceptual scope and sequence I created (for Language & Literature), where I differentiated concepts by phase or grade level, I haven't attached a phase or grade level to this skills progression because students develop skills at different stages. It's perfectly possible that a student in MYP 3 might be an expert at critical thinking, whilst a student in Grade 10 might still be a novice at research. I recommend using this skills progression alongside Alison Yang's ATL Smörgåsbord or Lenny Dutton's ATL Toolkit, both of which suggest specific activities which can be used to practice and develop the skills.
You can download the streamlined version or make a copy of the Google Sheet for the full version which includes every individual skill; the progression itself is incomplete, but there are a few examples to get started.
