THE Inner London Educe-. tion Authority's plans for 51 grammar and secondary schools to "go comprehensive" by 1970 will mean more places in Catholic schools, according to Mr. W. A. Fifer, secretary of the Westminster Archdiocesan Schools Commission,
Because most of the plans call for long-term growth, the Westminster and Southwark diocesan commissions cannot begin to estimate how many more places Catholic schools will receive.
At present they have room for only one in three of London's Catholic children.
An example of the way places will be increased is the Bishop Giffard School at Islington, now a three-stream secondary for boys and girls.
In ten years it will become a four-stream comprehensive for girls, occupying the former Our Lady of Sion Convent School and a vacated county school.
The old Bishop Giffard buildings will in turn be used for enlarging the St. William of York School, which will be adapted from a three-stream mixed secondary into a fivestream comprehensive f o r boys.
Again, the four-stream boys grammar, London Oratory in Chelsea, will be rebuilt on a site in Fulham as a six-stream comprehensive.
St. Aloysius College in Highgate will expand into a cornprehensive for boys. And the Cardinal Manning and Cardinal Vaughan Schools in Kensington will be combined.
"Of course size is indispensable to run a comprehensive," Mr. Elfer noted. "So where we have grammar or secondary schools that cannot be enlarged, they will be kept as they are for the time being, and no pressure is being put on them to change."
The Catholic schools in this category in the Westminster Archdiocese are: Sacred Heart Convent High School, Hammersmith; St. Aloysius Convent, Somers Town; Our Lady's Convent, Stoke Newington, and St. Victoire's Convent, Homerton.
In Southwark: St. Ursula's Convent, Greenwich; St. Joseph's Academy. Blackheath; Notre Dame High School, Southwark; La Retraite High School, Clapham; Clapham College, Notre Dame High School, Battersea, and Salesian College, Battersea.
