Education bosses say there have been no reports of the national Sats boycott hitting Hartlepool schools.
Across the country tens of thousands of people signed a petition supporting a boycott in protest over exams for six- and seven-year-olds.
The Let Our Kids Be Kids campaign wanted parents across England to keep their children off school today, saying they are "over-tested, over-worked and in a school system that places more importance on test results and league tables than children's happiness and joy of learning".
The petition, signed by more than 40,000 people, added: "We want our kids to be kids again and enjoy learning for learning's sake, not for Ofsted results or league table figures.
"Bring back the creativity and the fun - say goodbye to repetition and boredom."
However, a spokesman for Hartlepool Borough Council, said: "We have not been made aware of any school absences due to the protest against Sats.”
The Let Our Kids Be Kids group claims children are being asked to learn concepts that may be beyond their capability and becoming stressed and anxious.
These new Sats tests have been drawn up to assess children's grasp of the recently introduced primary school national curriculum, which is widely considered to be harder than the previous one.
Sats are taken by children aged six or seven in Year Two and then again in Year Six, aged 10 or 11, before a third set in Year Nine aged 13 or 14.
Shadow education secretary Lucy Powell said she did not condone the action but claimed ministers had "ridden roughshod" over the concerns of headteachers and parents about Sats.
Education Secretary, Nicky Morgan, warned that missing school even for a single day would be "harmful" and called for those behind the "damaging" campaign to reconsider their actions.
