Appearance
Mr. Ratburn's appearance consists of a green suit complete with a solid yellow shirt and bright red necktie (in the books, his uniform ranges to different colors). Being a rat, he has long whiskers, which he appears to keep trimmed.

He has brown clumps of hair in the books; although in the cartoon show, his hair was restricted to thin black lines. He also wears his shirts tucked into his pants and always wears a belt buckle with his pants. He also wears blue pajamas and in one episode he wore a turquoise night shirt  and another episode he also wore tan coloured sweater  and black pants and wear brown or black slippers

His casual clothing consists of a cream-colored T-shirt and faded blue jeans. For formal occasions Mr. Ratburn wears a charcoal or black Tuxedo jacket with a white Tuxedo shirt black bow tie and charcoal or black Tuxedo trousers.

When outdoors for something like fossil-hunting Mr. Ratburn wears a dark brown hat with a yellow line on the bottom of the tip of the hat going all around the tip. He also wears a very light yellow or beige shirt a dark blue scarf tucked into the shirt.

There is also a short-sleeved beige jacket with two pockets one on each side of the jacket and two shoulder straps one on each side of the jacket. He also wears blue shorts very light yellow or beige socks and light brown boots. He always carries a briefcase with him to class.

Personality
He tends to give out a lot of homework to the kids in his class, sometimes assigning two research projects in the same week. Because of these tendencies, he is often considered the strictest teacher at Lakewood Elementary School.

However, many of Arthur and his friends find out he's not as bad as they first thought, although the Brain seems to have no problem with him, but Buster has the strongest dislike for homework. Though he is a cool and calm character, in some dream sequences, he cackles uncontrollably.

Past life
When Mr. Ratburn was a baby, he was wearing a light blue sweater with a white collar, a red bowtie, white cloth diapers with pins, and bright red shoes and blue socks.

As a kid, he had two outfits: A school uniform that was colored blue like Glenbrook Academy's dress code and the uniform that had the school's badge on it. Then he had casual clothes; which he wore to events, like the Father's Day picnic. That consisted of a blue-buttoned shirt with a white shirt under it and blue pants.

He used to be a "fat rat", until he learned how to play ping-pong.

As a young adult, he attended Elwood City High School with Bailey, David Read , and Mr. Haney.

In college, he was in a band called the "Ratburn Rats".

Future Life
Not much has been seen about Mr.Ratburn's future. But if the future in the episode, "Buster Makes the Grade" happens Mr. Ratburn will continue his career as a teacher at Lakewood Elementary.

In Other media
In the Living Books computer games, he came out in Arthur's Teacher Trouble, even though there's a shadow look-alike of him walking outside while Arthur and Jane are out shopping for party supplies in Arthur's Birthday. He was voiced by David Kessler before the cartoon show replaced him with Arthur Holden.

In the later computer games (such as Arthur's Thinking Games), Mr. Ratburn's appearance was the same as he looked in the cartoon show.
