What other people have said

Our thanks to everyone who agreed to share their thoughts. All of the following reviews are from the last 3 calendar years:

"Really enjoyed the course. Would like to do advanced excel next."

Katherine Wheeler (NHS South, Central and West CSU)

"I had done a lot of online tutorials on SQL, so wasn't sure how beneficial attending the course would be for me. However I came away from it feeling a lot more confident in my ability to use SQL and thought it had been a really helpful and useful course to attend. My bosses recommended Wise Owl SQL training to me."

Rachel Hollis (NHS West Yorkshire ICB)

"It was a great course, very informative, and our trainer was great at being flexible to the group's ability and needs. Would highly recommend."

Kirsty Trent (Department for Education)

"I enjoyed the course and picked up loads of really useful tips. I am already beginning to use Power BI to produce new visualisations for data that I am currently analysing."

Simon Hart (Government Internal Audit Agency (GIAA))

"An excellent trainer who explained everything in a very engaging way. I was very unconfident with joins and aggregate functions before the course but now feel competent with them thanks to him."

How our training courses work

Below are some notes on how Wise Owl courses work, to help you decide whether they're for you or not.

What you'll need

If you book on a classroom course, the only thing you need to bring to the course is ... yourself! We even provide a notepad and a suprisingly nice pen for you to take notes with.

For online training you'll need two things:

  1. A good internet connection (otherwise you'll have a frustrating time); and
  2. A second screen (a requirement, not a nice-to-have!)

You can see full details of our online course requirements here.

When you book a place

If you book a place on one of our courses:

  • For classroom courses we will send out a joining email. That's it!
  • For online courses we will get in touch to organise a half-hour pre-course check to iron out any connection problems before the course (rather than during it).

Whatever type of course you book, we will also send you out a reminder a few days before the course is due to take place - not that (we hope) you'll have forgotten!

What you won't need

For classroom training, you won't need a computer - we (obviously) will provide that. However, you're welcome to use your own laptop if you prefer, providing that you have the correct software installed.

For online training you will need a computer, but you won't need to have any software installed.  This is because you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed.

The start of the course

For online courses you will be able to join up to half an hour before the course begins. This will give you time to:

  • familiarise yourself with the set-up;
  • meet your trainer; and
  • get to know the other delegates!

For classroom training it's always nice if people arrive a bit early too, to give people time to meet each other (and drink coffee).

You'll be given a full colour courseware manual, an exercise booklet to go with the course and a USB stick for taking course files away (we'll post all this to you for online courses).

After the course

After the course finishes you'll receive a digital certificate proving your attendance (we will gladly send a paper copy on request also).

We don't have any formal arrangement for answering questions after the course, but if you get stuck on something and email your trainer they should (and nearly always do!) respond as quickly as their training schedule allows.
