I don't think there is an alternative per se. But you would need to look at what a 'Champion' school is, what resources they are offering, and find alternatives
If anyone's interested, it looks like you can attend their 'Train The Trainer' course for £240.

I would look at what they are teaching and identify what is problematic about it. I'm not sure it's easy to reject them outright without pointing to what specifically about the Champion Programme is regressive.
It looks like these are some of the resources they use

In particular this one:

Note it was co-written by Gendered Intelligence.
There are some odd terms there:
"Homosexual
this might be considered a more medical term used to describe someone who has an emotional romantic and/or sexual orientation towards someone of the same gender. The term ‘gay’ is now more generally used"
What's 'medical' about 'homosexual'?
'A cisgender person
someone whose gender identity is the same as the sex they were assigned at birth. Non-trans is also used by some people'
'assigned at birth' is an offensive appropriation of intersex conditions.'
'Gender variant
someone who does not conform to the gender roles and behaviours assigned to them at birth. '
Gender roles & behaviours are NOT NOT NOT assigned a birth.
'This is usually used in relation to children or young people'
Whatt what what?
"Intersex
a term used to describe a person who may have the biological attributes of both sexes or whose biological attributes do not fit with societal assumptions about what constitutes male or female. Intersex people can identify as male, female or non-binary"
What the fuck no, this is horrible. Intersex refers to people with variant sex characteristics. It does not mean you are of both sexes you ignorant bastards. And it's nothing to do with 'societal assumptions', it's variant biology. Society does not ASSUME that people are androgen-sensitive, that's simple fucking biology (such that if you are androgen-insensitive you have an intersex condition, it's not an assumption)
'• not everyone identifies with the sex that they were assigned at birth'
sex is not assigned. Sex is innate.
'Transgender man a term used to describe someone who is assigned
female at birth but identifies and lives as a man. '
not fucking assigned.
'A transsexual person
this was used in the past as a more medical term (similarly to homosexual) to refer to someone who transitioned to live in the
‘opposite’ gender to the one assigned at birth. This term is still used by some although many people prefer the term trans or transgender'
No no no. Some self-identifying transsexuals understand 'transsexual' to mean that you have had surgery to change gender. Why are they erasing this? And again the assinged bullshit.
'Gender dysphoria
used to describe when a person experiences discomfort or distress because there is a mismatch between their sex assigned at birth'
It's not assigned
'Pronoun
words we use to refer to people’s gender in conversation – for example, ‘he’ or ‘she’''
Do you even English? A pronoun is literally a substitute for a noun. They are not used to 'refer' to a gender, it just happens that most pronouns are gendered, but that's not their purpose!
There's a bit of 'transgender people will kill themselves' propaganda there.
Some of the rest of it looks ok.
