The Catholic education sector will be damaged beyond repair if academic selection remains, according to most Catholic primary school principals the BBC has reported.
In a Catholic Principals Association survey, 63% agreed that failure to move away from academic selection would have adverse consequences for the sector. Although only 28% percent of 400 Catholic principals responded to the association's questionnaire.
76% agreed too much deference was shown to grammar schools.
More than 7,000 children have sat the first of this year's unofficial transfer tests which took place on Saturday the 9th of November.
The AQE says the number registering to do the tests has risen, but it is not possible to say if that means more children overall are choosing to go through academic selection, because there is an overlap of children doing both sets of tests (The AQE Common Entrance Assessment & the PPTC GL Assessment).
The GL Assessment, used mostly by Catholic schools, will take place on Saturday the 16th of November.
Application forms are now available for parents to register their child for the AQE Common Entrance Assessment (CEA).
You can download the Registration Form from the AQE website, from an AQE Grammar School or from the AQE Office. Some Primary Schools may also be able to give you a form. Photocopies/black & white printed forms are perfectly acceptable.
The closing date for applications is the 13th of September 2013
Results day has finally arrived. Good luck to all the children & parents eagerly waiting for the postman to arrive.
We hope you get the grade/score you need for your preferred school.
Remember to visit our School Intake Information page for all the highest and lowest scores or grades that each grammar school accepted for the previous 3 years. This can help guide you with your School choices.
