In some dyslexic kids the “self learning cycle” that propels reading acquisition in non-dyslexic kids will kick in after a certain amount of remediation. I’ve seen it happen with a very bright, mildly dyslexic kid after the first three levels of Sounds in Syllables, the program ASDEC trains its practitioners in. This kid is able to read the usual late elementary grades novels. More importantly, they ARE reading those novels. With explicit teaching, reaching mastery of skills, and then lots of practice, they are now able to self-learn remaining patterns and build orthographic mapping.
If your kid hasn’t reached that point where it feels like they are “taking off,” and they haven’t finished every level of whatever program the tutor is using, then unfortunately I think you keep up the tutoring. You can give strategic breaks - two weeks here, two weeks there - but pick back up.
If you don’t know what level your kid is on, or what they are being taught and what skills remain, ask. If your tutor/therapist is unable to tell you then look for someone who can.
