I firmly believe teaching is a vocation, and teachers are born, not made. My formal teacher training put me right off teaching and I abandoned it for a number of years until I had raised my children and re-discovered my love of teaching. I then re-trained as a Montessori teacher, which fitted perfectly with my beliefs about child rearing and education.
Later, during the years when I ran performing arts classes and employed professional performers to teach, I instinctively recruited those with whom I felt a rapport, despite their lack of formal teacher training, and in 99% of cases they proved to be inspirational teachers in their field.
Many have gone on, once past their own performing prime, to take their PGCE and to teach in State schools. I also have 2 former students; both 'difficult' school pupils, repeatedly suspended from school, who found sanctuary and belief in themselves with us on a Saturday, who have recently graduated as teachers and are by all accounts showing excellent promise. I feel very proud to have been part of the teams who gave them back their self-respect, and gave them the desire to do the same for others.
I do however have one major concern, and that is the appalling level of the majority's spelling, grammar and basic maths skills. This is a serious failing on the part of our education system and has to be addressed. Unless primary school teachers know the difference between 'to' and 'too' or between 'there' 'their' and 'they're' (demonstrated daily by these wonderful women on Facebook!) or how to work out percentages, etc., what hope is there that standards will be raised? Minimum standards are therefore essential, but if one is not to exclude potentially brilliant teachers such as those I have described, I guess remedial teaching is required for trainee teachers!! What a mess.
