CLP Mastery 2023 starts with the 3 month training phase.  This begins with our first meeting on Wednesday 6th September 2023, and runs until 29th November 2023, with weekly Teams meetings every Wednesday at 2pm UK time. These are recorded and put on the website so anyone who can’t attend can catch up, and people who were in the meeting can view the video again.

The support phase runs from Thursday 30th November until Tuesday 3rd September 2024.

You’ll be joining our current trainees, and former trainees who like to keep up to date on an Annual Access subscription. We have 27 people already in the course, which makes for lively and interesting meetings.

If you are funding CLP Mastery yourself, please email us on rather than paying via this page.

Enrolment for CLP Mastery 2023 ends 6th September 2023, 12 noon UK time

What you get with CLP Mastery

A 13-module intensive training course over 3 months/ 13 weeks, with 9 months of ongoing support.

Lots of contact with trainers

Online meetings every week in the training phase

A further 9 months implementation phase, with monthly online meetings, totalling 22 meetings where you can meet your fellow trainees, ask questions, take “priming” exercises, feed back any problems to us so we can update the course and everyone learns.

Access to our unique training materials

  • infographics and sketchnotes to help with summarising and understanding key concepts
  • screencast demos showing you how to search for information quickly
  • flowcharts, look-up tables and comparison documents to help you classify quickly and accurately
  • our famous “cheat sheets” to help you convert GHS classifications into label information
  • other tools for classification, labelling and producing SDSs, or checking what your software is producing

The practice areas

Each module has a dedicated practice area where you can test and improve your skills.  These will help you practice parts of the module, or all of it, and usually work from easy questions to more difficult ones, so you can see how you’re making progress.

There’s immediate feedback, and nobody except you knows what you’ve done – no need to feel embarrassed.  In fact, making mistakes can help you learn more than getting everything right!


Some of the modules include assignments where you have to produce labels or a Safety Data Sheet.  These are marked by hand and you get personalised individual feedback by email.

The quizzes

Every module also has a quiz, with immediate feedback, and sometimes personalised feedback by email if we think it will help you understand a concept better.  We reserve the right to give you extra questions to check you’ve really grasped a concept or skill!

The Implementation Knowledgebase

This sits outside the training course itself, and includes a jargon buster for all those pesky acronyms, everything we know at the moment about certain product types, FAQs, the occasional worked example etc. 

As one of our lovely “live” trainees said “it’s like looking into your brain!” except now it’s got even more data from even more brains included!

Chemicals Coffee Time Weekly Email Newsletter

Our trainees also receive free access forever to our weekly email newsletter, which is a great way to keep up to date with the changes in regulations and classification which come out of GHS itself, and also out of the EU (ECHA) and GB (the HSE).  And don’t forget the Weekend Read, the Recipe, and the Reasons to be Cheerful funny video.

Here’s what some of our trainees have to say about CLP Mastery:

Really enjoyed the course and when the darker nights come, and I find more time will run through it again as I am sure I will pick up more.   Thanks for your patience and will see you at next meeting if not before.” Tony M., Lakeland Chemicals, 2023

I came into the course with little to no experience other that some self-teaching and; hopefully; some common sense. I was concerned that my lack of chemistry background would be a detriment to my progress and I would say that was probably my weak area overall. I like the module structure of the course and the bite size chunks. I think the newer way of classifying with the accompanying pack is a stroke of genius – it really takes the worry out of it and simplifies it so it is much less daunting. Ali’s expertise coupled with your experience is a great combination and was invaluable throughout – your skill sets compliment each other to the benefit of your students. Overall if I think back to where I was this time last year, my knowledge has vastly improved as has my confidence. That is down to your training course entirely and thank you for allowing me to run through it twice as I needed it for the classification section especially” Chris U, Pelgar, 16th January 2023   

I have to say I didn’t think the course could get any better from last time but its brilliant especially dealing with the Brexit stuff, thank you so much“.  Yannick G, 10th January 2023 

Dear Janet and Alison, I wanted to thank you both for all the great work and support you provided your students (and me in particular) with over this year. It was indeed a pleasure for me to be your student :); I am confident that the next year your CLP University will be growing and developing further.” Serhii L., Juul Labs, 21st December 2022 

It’s been pleasure to attend the class and invest my time in this very in-depth master class. I enjoyed going through all the modules and it’s practice areas which I could then apply to quizzes at the end of each module. I loved to participate in our discussion of the results (of each participants) and finding out that every person have different approach to problem solving and also have different point of views to various CLP topics.” Zuzana Hovorka, Bartoline Ltd, 12th September 2022 

Janet has created a fantastic online course with modules surrounding CLP”.  Lizi Jenkins, NextGen 360, 11th May 2020

CLP Mastery is excellent, very thorough and thoughtfully put together.  Just when I am trying to understand something you come up with an example that gives me a eureka moment.  Although it is a serious subject, you do make it fun (I wasn’t aware that was possible) and enjoyable.”  Dr John Smith, Aztec Oils, 3rd June 2020
