Hi @sammecooper, it is definitely a good idea to optimise your page titles to improve SEO. These can have a great impact on SERP ranking as well as CTR.
Firstly as has been mentioned by others here, it is very important to include your target keyword in the title "Training and Engagement" it is also then good to follow up with a more engaging phrase that will encourage people to click on your page. Something like you have already as a combination of both "Training and Engagement: Providing skills to make the change stick" (don't be scared to use longer titles but keep the URL as short as possible (also including the target keywords)).
It may also be useful to have a read of this post about stop words that are ignored by search engines https://www.semrush.com/blog/seo-stop-words/
Other points to test out for increased CTR (which can lead to better ranking in SERP) is to use emotional SEO power words, emoji and even [brackets] in your title. These have been shown to increase CTR in many cases.
Also worth mentioning this recent update by Google where HTML title tags are being replaced by the H1 of the page for SERP listings https://www.seroundtable.com/semrush-data-titles-google-32004.html
Good luck with your optimisation, it is an ongoing process so don't give up if you don't see immediate results!
