Lincolnshire's Social Services Department has failed to improve in the past year, according to national ratings.
It follows news that the county's budget for social services is £20m below the national average.
The department has retained its one star rating which it achieved last year.
In the figures a zero rating is considered to be poor with three stars being excellent.
Each department has been judged on how well they are serving people .
The results show that Lincolnshire services for both children and adults are serving some people well but there is also room for improvement.
It comes a week after the department was criticised in a government report highlighting the number of outstanding cases and a chronic shortage of social workers.
The report also noted the council's social services spending was 14% less than the national average.
