Stawell Primary School has the biggest number of preps with 44 split into two classrooms of 22 students each.

St Patrick's Primary School has welcomed 26 new children to its school while Stawell West has 20 of its own.

"It is my great pleasure to welcome the prep students starting their educational journey at our fantastic Victorian schools," Premier, Denis Napthine said.

"I want to wish them all the best as they form lifelong friendships, have great adventures and develop a love of learning.

Minister for Education Martin Dixon said he would like to also welcome back the 890,600 students returning to school after the summer break, and hope that they are rested, energised and ready to go.

"The start of the school year is an exciting time - and I am sure everyone is eager to get the year going," he said.

"It's the start of a new chapter for many and I'm sure right across Victoria there will be plenty of proud parents waving goodbye at the school gate or the bus stop.

"There may also be some nerves - for parents and preps alike - but I'm sure they'll settle into school life quickly."

Preps aren't the only ones starting their school careers this year - about 2,500 graduate teachers have started in schools.

And it wasn't just preps and year sevens who felt the first day jitters with those still too young for school starting kindergarten.

Minister for Children and Early Childhood Development Wendy Lovell wished all children well as they embarked on this pivotal year in their education.

"This is a very exciting time for families who - judging from record kinder participation rates (98.2 per cent in 2013) - understand and appreciate the value of a high quality kindergarten education," she said.

"Children attending kindergarten have time to learn, socialise and grow and are better equipped to succeed at school.

"We know that high quality early childhood education is crucial for children in their early years as it helps them develop the skills they need to go on and thrive through their schooling years."
