From their website:
"Testing (October 2015) for entry to Year 7 in September 2016
Tiffin School’s proposed Admissions Policy for entry in September 2016 will be published on the school website at the beginning of December 2014, for consultation.
However, as the School proposes to change the method of testing, the Governors wish to give prior notice of this.
The proposal is that there will be a first stage of testing, which will comprise English and Maths multiple choice questions.
For those invited to the second stage of testing, there will be written exam papers in Maths and English.
The English and Maths questions will be designed to reflect the primary school curriculum and be of a standard that will be appropriate to determine admission to the School.
Further details will be available in December 2014, when the proposed Admissions Policy for entry in September 2016 is published for consultation on this website.
Ah, thanks CC! Having almost finished the campaign (until my next one that is), I have not kept up to date and didn't check their website. Looks like they are moving towards the Suttons consortium way.
