The fact that we no longer have interviews for would-be teachers is "a regressive step," according to Joe O'Toole, general secretary of the INTO. "Interviews are crucial," he says. "The last thing we need is a profession of high-flyers with no common sense. Teachers must reflect the community. If we select on the basis of academic performance we are losing out on a lot of gifted and talented people." So, what makes a good teacher? "Academic and teaching ability apart, as a principal I used to look for enthusiasm, energy and interest," says O'Toole. "Teaching is physically and mentally tiring. You need enthusiasm because feedback comes in small doses. Teachers need to have a wide range of interests and a passion for something, be it astronomy or zoology, so they can pass this to a child."

What about patience? "Teachers need to tolerant," says O'Toole, "but patience is a quality that can imply passivity."

What about a love of children - is that not necessary in order to be a good teacher? "You need to feel comfortable with children and be able to talk to them on their level," says Tony Bronell, Mary Immaculate's registrar. Teachers need the ability to develop the potential of every child, he says. "This is not easy, especially in large classes."

And teaching's greatest buzz? "Seeing a child succeed at something often against the odds," replies O'Toole.
