Online vs in-person assessments

Two ways of assessing, one shared standard

ADHD and autism assessments can be carried out online, in person, or through a mix of both. The format is mainly a matter of delivery and convenience — a properly conducted assessment, whichever way it is delivered, should still follow recognised clinical frameworks, such as NICE guideline NG87 for ADHD and NICE guidance for autism, and be carried out by appropriately qualified and registered clinicians.

Neither format is inherently "better" in every case. What matters most is the thoroughness of the assessment, the qualifications of the clinician, and how well the process is suited to your individual needs.

What online assessments typically involve

Online assessments are usually conducted over secure video calls, sometimes combined with online questionnaires completed in your own time. This can include:

• Video consultations with a clinician
• Digital versions of standardised questionnaires and rating scales
• Remote input from family members, partners or teachers, often via online forms
• Secure sharing of reports and follow-up communication

Online assessment can be a practical option for people who live far from specialist services, have mobility or health issues that make travel difficult, or simply prefer the flexibility of appointments from home. It has become more widely used and accepted in recent years, though some clinicians and services may still recommend or require an in-person element for certain assessments, particularly where direct observation is considered important.

What in-person assessments typically involve

In-person assessments take place at a clinic or healthcare setting and may include:

• Face-to-face interviews and observation
• Structured interactive activities, particularly relevant for autism assessments
• The opportunity for a clinician to observe body language, social interaction and behaviour directly in the room
• In-person completion of certain assessment tools that may be harder to replicate remotely

Some people find in-person appointments easier for building rapport, especially children or those who find video calls tiring or difficult to engage with. Others may find travel, time off work, or environments outside the home more challenging.

Comparing the two formats

Some practical, non-clinical points to consider:

• Accessibility: Online formats can reduce travel time and may suit people in rural areas or with limited mobility. In-person appointments may suit those who find video communication harder, including some autistic people or those with sensory sensitivities to screens.
• Comfort and environment: Some people feel more relaxed being assessed from their own home; others prefer a neutral clinical setting.
• Technology: Online assessment requires a reasonably reliable internet connection, a private space, and comfort using video call software.
• Assessment type: Some parts of an autism assessment, in particular, may benefit from in-person observation, depending on the tools used and the clinician's judgement.
• Availability: Provider availability for either format can vary, so it's worth asking directly what options a service offers.

Questions worth asking a provider

• Is the assessment fully online, fully in-person, or a hybrid of both?
• If online, what platform is used, and how is confidentiality protected?
• Will there be any requirement for an in-person visit at any stage?
• How are the same standardised tools and observations achieved remotely, if relevant?
• What support is available if technical issues arise during an online appointment?

Does format affect diagnosis?

A well-conducted assessment, whether online or in-person, should apply the same clinical rigour and use validated, appropriate tools. The format itself does not determine whether someone receives a diagnosis; what matters is a thorough gathering of information across settings and time, sound clinical reasoning, and a properly qualified clinician making the judgement.

If you have particular needs — for example, sensory sensitivities, anxiety about travel, or difficulty communicating over video — it's worth discussing these with a provider in advance so they can adapt their approach where possible.

A note on choice and comfort

There is no universally "right" choice between online and in-person assessment. The best option is the one that allows you, or your child, to engage as fully and comfortably as possible with the process, with a regulated and appropriately qualified clinician. If you're unsure, ask providers about their experience with both formats and how they decide which is most suitable for a given situation.

As always, speak to your GP if you have questions about which approach might suit your circumstances, or about any health concerns more broadly.

How providers decide which format to offer

Many providers now offer a choice, or a hybrid approach combining both formats, but the reasons behind their recommendations aren't always obvious to patients. Some clinicians prefer at least one in-person session for certain autism assessments because particular observational tools were originally designed and validated for face-to-face use, and adapting them for video calls requires additional care and experience. Other clinicians are confident delivering the entire pathway remotely and have adapted their practice accordingly. Neither approach is automatically wrong; what matters is that the provider can explain their reasoning and that the chosen format still allows a thorough assessment.

Practical tips for online appointments

If you're preparing for an online assessment, a few practical steps can help things go smoothly. Test your internet connection and device beforehand, find a quiet and private space where you won't be interrupted, and have any documents or notes ready to reference or share on screen if needed. If you use assistive technology, or find video calls tiring for sensory or attention-related reasons, let the clinic know in advance so they can plan accordingly, for example by building in extra breaks or adjusting appointment length.

Practical tips for in-person appointments

For in-person appointments, plan your travel with some extra time built in, particularly if unfamiliar journeys or waiting rooms feel stressful. Ask the clinic in advance what the environment will be like, whether there is a quiet waiting area, and whether you can bring headphones, fidget tools, or other comfort items if that would help you feel more at ease. If you have specific sensory sensitivities, such as to bright lighting or noise, mentioning this beforehand may allow the clinic to make small adjustments.

When mixed approaches make sense

Some assessments blend formats deliberately, for example using online sessions for interviews and information-gathering, then an in-person session for direct observation activities relevant to autism assessment. This hybrid model can combine the convenience of remote appointments with the benefits of face-to-face observation where it matters most clinically. If a provider offers this, ask them to explain clearly which parts will happen online and which in person, and why, so you know what to expect at each stage.
