The Sussex Schools' FA will clampdown on discipline after three players were sent off in two county finals at Peacehaven.
Two red cards were shown for persistent dissent when Seaford Head beat Varndean College (Brighton and Hove) 3-0 in the under-19s' League Cup final.
Another player was dismissed for an alleged elbow as Brighton, Hove and Sussex Sixth Form College pipped Bexhill 1-0.
Alan Ball, SSFA and English Schools' FA administrator said: "The behaviour and attitude of some of the players was unacceptable.
"I hope it was a blip but we will, as an Association, try and make sure it doesn't happen again.
"Players who get involved in that type of behaviour could end up spending their careers suspended.
"Young people ape what they see on the television but our priorities are to provide an education and set standards."
BHASVIC manager Andy King, who also witnessed the Seaford versus Varndean match, said: "There is no place in schools football for that. I believed the lad, who I feel elbowed our player off the ball, was showing his frustration.
Captain Steve Metcalfe scored the winning goal for BHASVIC.
King said: "Steve has had a super season for us. His goal was a bit of a fluke. He smacked a free-kick that bobbled and everyone missed it.
"We won it the year before last and are delighted to win it again. The coaching my players received from Dave Jupp, who is with the Albion Football In The Community Scheme, helped."
BHASVIC finished third in the Academy League and produced Scott Kirkwood, who played against Bexhill, for English Colleges.
King said: "Scott followed a few students who have received national; recognition in recent years like Lee Newman, who also faced Bexhill, Tom Djamaluddin and Ollie Rowland."
Bexhill coach Dave Brown added: "We accept the sending off decision. It was spotted by the linesman. It was a shame because it soured the spirit of the game for the last few minutes. We had a makeshift side because of injuries."
Seaford Head boss Jenny Thompson praised her side for keeping cool.
She said: "My side won the Sussex Sixes and were determined to win again.
"They were disciplined and incredibly focussed."
Lee Plastow put Seaford Head in front and Tom Callaghan grabbed adouble to clinch the cup.
Brighton and Hove under-12s beat Mid Sussex 2-1 at Hassocks to lift the Patrick Haugh Trophy.
Sussex Schools' under-19s had mixed fortunes at the Festival of Football in Pakefield, Lowestoft, Suffolk.
Twins Richard and Simon Lewis (Chichester Tech) made their Sussex first team debuts together in a 5-2 victory over Hertfordshire.
Matt Simpson (BHASVIC) put the county ahead before Herts equalised. A quick throw out by goalkeeper Gary Elliott (Steyning) set up Simpson and Stephen Graham (Park College, Eastbourne) restored Sussex's advantage.
Simpson grabbed his second after a delicate flick from Michael Death (Chich Tech). Herts pulled a goal back before half-time and two goals from Graham sealed it.
Nick Fogden (Varndean) and Russell Kirby (Steyning) were commanding figures in Sussex's defence. Captain Seb Kazemi (Varndean) and Graham impressed in midfield.
They were defeated 2-0 by Shrophire with goalkeeper Matt Brown (Park College, Eastbourne), an international triallist, in form.
Sussex player-of-the-festival Graham scored the winner in a 1-0 victory against Lincolnshire and Ash Dorrington (Steyning) caught the eye at full-back.
Matt Simpson (Collyers, Horsham) joined Matt Simpson (BHASVIC) upfront in a 2-2 draw with Greater Manchester. Scott Kirkwood and Graham scored for Sussex. Jordan Willis (Felpham College) made his debut.
Sussex B drew 1-1 against Shropshire when Willis scored and Matt Hurley (BHASVIC) was outstanding. Peter Baker (Varndean) and Darryl Hunter (Steyning) debuted.
They then overcame Surrey 4-1 with John Steele (Sussex Downs), two, Willis and Peter Baker (Varndean) on target.
Manager Ian Hutchings said: "My players have shown that they can compete at the highest level. In the last two weeks they have taken the national finalists Shropshire and Suffolk right to the wire. They were two very close games, which could have gone for rather than against them.
"We have a handful of players whom we believe will be pushing for international recognition next year. I'd like to thank assistant manager and coach Bob Bantock for his outstanding contribution."
