Emsi have recently added an interesting new metric to our Job Posting Analytics data, which means we can more easily track what we are calling "Hot and Cold Skills".

By this we mean the growth or decline in employer demand for skills over a set timeframe, with those that have seen the highest growth being considered "Hot Skills", and those that have seen the biggest decline described as "Cold Skills". This is a fascinating way not only of tracking recent employer demand, but also of giving us some clues as to how skills demand might be shaping up as we look to the future.

In the chart below, we've split out occupations into those considered:

  • high,
  • middle and
  • lower skilled,

based on the Standard Occupation Classifications (SOC 1-3 are high skilled occupations; 4-6 are middle skilled; and 7-9 are lower skilled).

We have then looked at the percentage increase or decrease in the number of times a skill appears in our job postings data over the last 12 months, excluding skills that appear in less than 500 postings to avoid low-demand skills skewing the data.

You can toggle between skills seen in online postings for high, middle and lower skilled jobs by clicking on the dropdown menu on the chart:

High Skilled Jobs 

Looking at high skilled jobs first, there are a few skills that make it into the Top 15 Hot Skills that may be something of a surprise -- for instance Small Animal Care, which saw growth in postings of 121.6%. However, as we might expect the list is dominated by digital and tech skills. These include:

  • Zoom (Video Conferencing Tool) (158.2%);
  • Broadband (153.4%);
  • Infrastructure as Code (IaC) (128.5%);
  • Azure DevOps (115.6%);
  • Power BI (113.8%);
  • Data Engineering (112.1%); and
  • Terraform (101.4%).

However, what the data also shows is that there are a number of digital and tech skills that have seen a decline in demand over the last year. These include:

  • JQuery (-24.1%);
  • ASP.NET MVC Framework (-24.6%); and
  • Ajax (Programming Language) (-28.3%).

This very neatly demonstrates how the data can highlight possible future trends, particularly in something like digital jobs where new technology and software mean that skills expectations and competencies are constantly changing.

Middle Skilled Jobs 

Moving on to Middle Skilled jobs, the most obvious thing to note is the growth in Vaccination which has -- for obvious reasons -- seen growth in demand of 477.9%.

The rest of the skills seem to cover a more diverse range of jobs than the high skilled jobs data, although a couple of digital and tech skills -- Google Workspace (162.5%) and Cybersecurity (158.6%) -- do make it into the Top 15.

If anything, the data for the 15 Cold Skills provides more points of interest, particularly as there are a number of skills connected with health and care that have seen a significant fall in demand. These include:

  • Nursing Care (-14.5%);
  • Dementia Care (-14.8%);
  • Venipuncture (-19.9%);
  • Phlebotomy (-21.3%);
  • Hydrotherapy (-22.8%); and
  • Spinal Cord Injuries (-25.7%).

Here we see how the data can reflect what we hear anecdotally or in the media, particularly the decline in Venipuncture and Phlebotomy, which is presumably connected with the fact that doctor's surgeries and hospitals have had to postpone blood tests, apparently due to a shortage of sample bottles.

Lower Skilled Jobs 

Finally we can look at lower skilled jobs. There are some skills in this section which may seem surprising, given that these are in lower skilled jobs, such as Talent Management (570.9%) and Banking (221.3).

This is because one of the three SOC codes we've used to define lower skilled jobs is Sales and Customer Service Occupations, which will include some of these sorts of skills.

Less surprising is the appearance of a number of skills connected with the hospitality sector, such as

  • Bartending (485.0%);
  • Grilling (392.5%);
  • Coffee Making (235.2%); and
  • Chain Restaurants (228.7%).

As for the 15 Cold Skills, it includes a diverse array of skills, with:

  • Telemarketing (-13.2%);
  • Agriculture (-14.6%);
  • Water Treatment (-21.3%); and
  • Nursing (82.7%)

These are among some of the most interesting declines in demand.

We thought it would be helpful to explain how we tier our latest education news content and how you can get involved and understand how you can read the latest daily Further Education news and how we structure our FE Week of content:

Main Features

Our main features are exclusive and are thought leadership articles and blue sky thinking with experts writing peer to peer news articles about the future of education and the future of work. The focus is solution led thought leadership, sharing best practice, innovation and emerging strategy. These are often articles about the future of education and the future of work, they often then create future education news articles. We limit our main features to a maximum of 20 per week, as they are often about new concepts and new thought processes. Our main features are also exclusive articles responding to the latest education news, maybe an insight from an expert into a policy announcement or response to an education think tank report or a white paper.

FE Voices

FE Voices was originally set up as a section on FE News to give a voice back to the sector. As we now have over 3,000 newsrooms and contributors, FE Voices are usually thought leadership articles, they don’t necessarily have to be exclusive, but usually are, they are slightly shorter than Main Features. FE Voices can include more mixed media with the Further Education News articles, such as embedded podcasts and videos. Our sector response articles asking for different comments and opinions to education policy announcements or responding to a report of white paper are usually held in the FE Voices section. If we have a live podcast in an evening or a radio show such as SkillsWorldLive radio show, the next morning we place the FE podcast recording in the FE Voices section.

Sector News

In sector news we have a blend of content from Press Releases, education resources, reports, education research, white papers from a range of contributors. We have a lot of positive education news articles from colleges, awarding organisations and Apprenticeship Training Providers, press releases from DfE to Think Tanks giving the overview of a report, through to helpful resources to help you with delivering education strategies to your learners and students.


We have a range of education podcasts on FE News, from hour long full production FE podcasts such as SkillsWorldLive in conjunction with the Federation of Awarding Bodies, to weekly podcasts from experts and thought leaders, providing advice and guidance to leaders. FE News also record podcasts at conferences and events, giving you one on one podcasts with education and skills experts on the latest strategies and developments.

We have over 150 education podcasts on FE News, ranging from EdTech podcasts with experts discussing Education 4.0 and how technology is complimenting and transforming education, to podcasts with experts discussing education research, the future of work, how to develop skills systems for jobs of the future to interviews with the Apprenticeship and Skills Minister.

We record our own exclusive FE News podcasts, work in conjunction with sector partners such as FAB to create weekly podcasts and daily education podcasts, through to working with sector leaders creating exclusive education news podcasts.

Education Video Interviews

FE News have over 700 FE Video interviews and have been recording education video interviews with experts for over 12 years. These are usually vox pop video interviews with experts across education and work, discussing blue sky thinking ideas and views about the future of education and work.


FE News has a free events calendar to check out the latest conferences, webinars and events to keep up to date with the latest education news and strategies.

FE Newsrooms

The FE Newsroom is home to your content if you are a FE News contributor. It also help the audience develop relationship with either you as an individual or your organisation as they can click through and ‘box set’ consume all of your previous thought leadership articles, latest education news press releases, videos and education podcasts.

Do you want to contribute, share your ideas or vision or share a press release?

If you want to write a thought leadership article, share your ideas and vision for the future of education or the future of work, write a press release sharing the latest education news or contribute to a podcast, first of all you need to set up a FE Newsroom login (which is free): once the team have approved your newsroom (all content, newsrooms are all approved by a member of the FE News team- no robots are used in this process!), you can then start adding content (again all articles, videos and podcasts are all approved by the FE News editorial team before they go live on FE News). As all newsrooms and content are approved by the FE News team, there will be a slight delay on the team being able to review and approve content.
