When you are adding evidence for a child on the English EYFS curriculum you have the option to link to nine coloured balloons.
These are The Characteristics of Effective Learning (CoEL)

Each colour refers to an Area of Learning and Development
Blue – Playing and exploring – Engagement
Green – Active learning – Motivation
Purple – Creating and thinking critically – Thinking
Within each area the initials refer a specific area
FE – Finding out and exploring
UK – Playing with what they know
HG – Being willing to ‘have a go’
BI – Being involved and concentrating
KT – Keeping trying
EA – Enjoying achieving what they set out to do
HI – Having their own ideas
LN – Making links
CW – Choosing ways to do things
You can select to link a piece of evidence to any of these areas.
