At Farnborough, we used to be valid in ADC, (now ADV/ADI) APP,(Farnborough and Odiham - separate validations), APS (Farnborough and Odiham), PAR and ACS including 'autonomous' crossings of airways.
That was after the old 3 year ATCO Cadet course during which you gained all ratings (including ACP) apart from PAR.
